Birthday Cake

Description

Prince Remmarguts helped Uyuw successfully hold a concert in our previous story (POJ 2451), and ...that was the day of Uyuw's birthday.

Ting-a-ling, the chef was called on by Remmarguts. "You must prepare an immense birthday cake for lovely Princess Uyuw in a single day," said Remmarguts. Though Remmarguts' order is outrageous, the chef eventually rushed to buy flour, sugar, fat, and some other ingredients.

There had been chaos caused by war for quite a long time. The price of everything has been highly raised. Being the head accountant of country UDF – United Delta of Freedom, you must weight the cake carefully to make sure the chef did not perform a cheat on the ingredients.

The cake is made up of N levels. There is a 'cube' in each level, while the length of cube on k-th level (count from the topmost) is exactly k! For Remmarguts lives in an M-Dimension world unlike our, you should notice that the 'cube' here means M-Dimension cube, and the volume of a cube with length k is k ^ M.

You are to calculate the total volume of such an immense cake.
Input

You should read the number of test cases Z (Z <= 30) in the first line. Each of the following lines denotes a single test case, consisting of two integers N and M. We guarantee that 1 <= N <= 10 ^ 41 and 3 <= M <= 100.
Output

Output one line per test case, showing the total volume of that cake. We also guarantee that the volume is less than 10 ^ 250.

Yukari's Birthday 怎么来求的
Problem Description Today is Yukari's n-th birthday. Ran and Chen hold a celebration party for her. Now comes the most important part, birthday cake! But it's a big challenge for them to place n candles on the top of the cake. As Yukari has lived for such a long long time, though she herself insists that she is a 17-year-old girl. To make the birthday cake look more beautiful, Ran and Chen decide to place them like r ≥ 1 concentric circles. They place ki candles equidistantly on the i-th circle, where k ≥ 2, 1 ≤ i ≤ r. And it's optional to place at most one candle at the center of the cake. In case that there are a lot of different pairs of r and k satisfying these restrictions, they want to minimize r × k. If there is still a tie, minimize r. Input There are about 10,000 test cases. Process to the end of file. Each test consists of only an integer 18 ≤ n ≤ 1012. Output For each test case, output r and k. Sample Input 18 111 1111 Sample Output 1 17 2 10 3 10
Cake Pieces and Plates
Description kcm1700, ntopia, suby, classic, tkwons, and their friends are having a birthday party for kcm1700. Of course, there is a very large birthday cake. They divide the birthday cake into undistinguishable pieces and put them on identical plates. kcm1700 is curious, so he wants to know how many ways there are to put m cake pieces on n plates. Input In the only input line, there are two integers n, m (1 ≤ n, m ≤ 4 500), which are the number of the plates and the number of the cake pieces respectively. Output If the number of ways is K, just output K mod 1000000007 because K can be very large. Sample Input 3 7 Sample Output 8

Share the Cakes
问题描述 : Lunar Rose is a pure and kind girl who was born in a serene town on, with surprising coincidence, the Mid-autumn Festival that year. Therefore, on each of her birthday, she enjoys two cakes: for the birthday, and for the festival. This year, Lunar would like to share the cakes with Jaddy, her boyfriend, on the nice day, isn’t it so romantic? What is the tragedy, Jaddy screwed up, again: When Lunar placed two cakes on the table, she wanted Jaddy to cut the cakes for her so that they can both have half of the moon cake and so do the birthday cake. But Jaddy, as a lazy and impetuous guy, he just used a knife to cut them together easily, hence although the two cakes had been cut into two pieces each, they were not really uniform. What was worth? Lunar is a pretty perfectionist and suddenly quite angry with Jaddy due to his arbitrariness. Finally, Lunar chose to leave him. Stupid Jaddy! Jaddy became extremely regretful and distressing. Lunar, a softhearted girl, does not have the heart to make him so painful so that she’d like to give Jaddy a chance to do it again. However, she set a strict limit for this task: Jaddy can only use one cut to separate the two cakes into equivalent halves. Evil Ms. Rose! Both two cakes are convex polygons; the table and knife are both big enough and long enough thus can be considered as infinite planar and line. This way, tell Jaddy a strategy, which means a line, satisfying Lunar’s condition to cut cakes so that he can get her back. 输入: The first line of the input data is a positive integer T (T <= 100) indicating the number of test cases. Then T cases follow. Each test case contains description of two cakes (polygons): each polygon begins with an integer n which denotes the number of vertices, and then n pairs of integers (x, y) follows describing the coordinates of vertices counterclockwise. You may assume that each polygon has no more than 20 vertices and all the coordinates are in range of [-1000, 1000]. Besides, the two polygons can be separated by a line, without touching on any points of the line. 输出: The first line of the input data is a positive integer T (T <= 100) indicating the number of test cases.

Cut the Cake 的设计思路
Problem Description Today is the birthday of Mr. Bon Vivant, who is known as one of the greatest p鈚issiers in the world. Those who are invited to his birthday party are gourmets from around the world. They are eager to see and eat his extremely creative cakes. Now a large box-shaped cake is being carried into the party. It is not beautifully decorated and looks rather simple, but it must be delicious beyond anyone's imagination. Let us cut it into pieces with a knife and serve them to the guests attending the party. The cake looks rectangular, viewing from above (Figure C-1). As exemplified in Figure C-2, the cake will iteratively be cut into pieces, where on each cut exactly a single piece is cut into two smaller pieces. Each cut surface must be orthogonal to the bottom face and must be orthogonal or parallel to a side face. So, every piece shall be rectangular looking from above and every side face vertical. Figure C-1: The top view of the cake Figure C-2: Cutting the cake into pieces Piece sizes in Figure C-2 vary significantly and it may look unfair, but you don't have to worry. Those guests who would like to eat as many sorts of cakes as possible often prefer smaller pieces. Of course, some prefer larger ones. Your mission of this problem is to write a computer program that simulates the cutting process of the cake and reports the size of each piece. Input The input is a sequence of datasets, each of which is of the following format. n w d p1 s1 ... pn sn   The first line starts with an integer n that is between 0 and 100 inclusive. It is the number of cuts to be performed. The following w and d in the same line are integers between 1 and 100 inclusive. They denote the width and depth of the cake, respectively. Assume in the sequel that the cake is placed so that w and d are the lengths in the east-west and north-south directions, respectively. Each of the following n lines specifies a single cut, cutting one and only one piece into two. pi is an integer between 1 and i inclusive and is the identification number of the piece that is the target of the i-th cut. Note that, just before the i-th cut, there exist exactly i pieces. Each piece in this stage has a unique identification number that is one of 1, 2, ..., i and is defined as follows: * The earlier a piece was born, the smaller its identification number is. * Of the two pieces born at a time by the same cut, the piece with the smaller area (looking from above) has the smaller identification number. If their areas are the same, you may define as you like the order between them, since your choice in this case has no influence on the final answer. Note that identification numbers are adjusted after each cut. si is an integer between 1 and 1000 inclusive and specifies the starting point of the i-th cut. From the northwest corner of the piece whose identification number is pi, you can reach the starting point by traveling si in the clockwise direction around the piece. You may assume that the starting point determined in this way cannot be any one of the four corners of the piece. The i-th cut surface is orthogonal to the side face on which the starting point exists. The end of the input is indicated by a line with three zeros. Output For each dataset, print in a line the areas looking from above of all the pieces that exist upon completion of the n cuts specified in the dataset. They should be in ascending order and separated by a space. When multiple pieces have the same area, print it as many times as the number of the pieces. Sample Input 3 5 6 1 18 2 19 1 2 3 4 1 1 1 2 1 3 1 0 2 5 0 0 0 Sample Output 4 4 6 16 1 1 1 1 10
关于 Cut the cake
Problem Description Mark bought a huge cake, because his friend ray_sun’s birthday is coming. Mark is worried about how to divide the cake since it’s so huge and ray_sun is so strange. Ray_sun is a nut, you can never imagine how strange he was, is, and going to be. He does not eat rice, moves like a cat, sleeps during work and plays games when the rest of the world are sleeping……It is not a surprise when he has some special requirements for the cake. A considering guy as Mark is, he will never let ray_sun down. However, he does have trouble fulfilling ray_sun’s wish this time; could you please give him a hand by solving the following problem for him? The cake can be divided into n*m blocks. Each block is colored either in blue or red. Ray_sun will only eat a piece (consisting of several blocks) with special shape and color. First, the shape of the piece should be a rectangle. Second, the color of blocks in the piece should be the same or red-and-blue crisscross. The so called ‘red-and-blue crisscross’ is demonstrated in the following picture. Could you please help Mark to find out the piece with maximum perimeter that satisfies ray_sun’s requirements? Input The first line contains a single integer T (T <= 20), the number of test cases. For each case, there are two given integers, n, m, (1 <= n, m <= 1000) denoting the dimension of the cake. Following the two integers, there is a n*m matrix where character B stands for blue, R red. Output For each test case, output the cased number in a format stated below, followed by the maximum perimeter you can find. Sample Input 2 1 1 B 3 3 BBR RBB BBB Sample Output Case #1: 4 Case #2: 8

This Takes the Cake 怎么编写的呢
Description In the kingdom of Polygonia the royal family consists of the king, the queen, and the 10-year-old twins,Prince Obtuse and Prince Trisect. The twins are fiercely competitive, and on their birthday they always vie with each other for the biggest portion of the cake. The wise king and queen have devised the following way to prevent squabbles over the cake. One prince is allowed to cut the cake into two pieces, then the other prince gets to choose which of the two pieces he wants. Cakes in Polygonia are always in the shape of a convex quadrilateral (a four-sided polygon with each internal angle less than 180 degrees). Furthermore, local custom dictates that all cake cutting must be done using a straight cut that joins two vertices, or two midpoints of the sides of the cake, or a vertex and a midpoint. For instance, the following figure shows all the possible legal cuts in a typical cake. Your problem is to determine, for a number of different cakes, the best cut, i.e., the one that divides the cake into two pieces whose areas (we are disregarding the thickness of the cake) are as nearly equal as possible. For instance, given a cake whose vertices (when the cake is viewed from above) are located, in counterclockwise order, at the points (0, 1), (6, 0), (5, 2) and (2, 3), the best possible cut would divide the cake into two pieces, one with area 4.375, the other with area 5.125; the cut joins the points (1, 2) and (5,5,1) (the midpoints of two of the sides). Input Input consists of a sequence of test cases, each consisting of four (x, y) values giving the counterclockwise traversal of the cake's vertices as viewed from directly above the cake; the final test case is followed by a line containing eight zeros. No three points will be collinear, all quadrilaterals are convex, and all coordinates will have absolute values of 10000 or less. Output For each cake, the cake number followed by the two areas, smaller first, to three decimal places of precision. Sample Input 0 1 6 0 5 2 2 3 0 0 100 0 100 100 0 100 0 0 0 0 0 0 0 0 Sample Output Cake 1: 4.375 5.125 Cake 2: 5000.000 5000.000

Problem Description Today is Gorwin’s birthday. So her mother want to realize her a wish. Gorwin says that she wants to eat many cakes. Thus, her mother takes her to a cake garden. The garden is splited into n*m grids. In each grids, there is a cake. The weight of cake in the i-th row j-th column is wij kilos, Gorwin starts from the top-left(1,1) grid of the garden and walk to the bottom-right(n,m) grid. In each step Gorwin can go to right or down, i.e when Gorwin stands in (i,j), then she can go to (i+1,j) or (i,j+1) (However, she can not go out of the garden). When Gorwin reachs a grid, she can eat up the cake in that grid or just leave it alone. However she can’t eat part of the cake. But Gorwin’s belly is not very large, so she can eat at most K kilos cake. Now, Gorwin has stood in the top-left grid and look at the map of the garden, she want to find a route which can lead her to eat most cake. But the map is so complicated. So she wants you to help her. Input Multiple test cases (about 15), every case gives n, m, K in a single line. In the next n lines, the i-th line contains m integers wi1,wi2,wi3,⋯wim which describes the weight of cakes in the i-th row Please process to the end of file. [Technical Specification] All inputs are integers. 1<=n,m,K<=100 1<=wij<=100 Output For each case, output an integer in an single line indicates the maximum weight of cake Gorwin can eat.

Cut the Cake 代码的编写
Problem Description Today is the birthday of Mr. Bon Vivant, who is known as one of the greatest p鈚issiers in the world. Those who are invited to his birthday party are gourmets from around the world. They are eager to see and eat his extremely creative cakes. Now a large box-shaped cake is being carried into the party. It is not beautifully decorated and looks rather simple, but it must be delicious beyond anyone's imagination. Let us cut it into pieces with a knife and serve them to the guests attending the party. The cake looks rectangular, viewing from above (Figure C-1). As exemplified in Figure C-2, the cake will iteratively be cut into pieces, where on each cut exactly a single piece is cut into two smaller pieces. Each cut surface must be orthogonal to the bottom face and must be orthogonal or parallel to a side face. So, every piece shall be rectangular looking from above and every side face vertical. Figure C-1: The top view of the cake Figure C-2: Cutting the cake into pieces Piece sizes in Figure C-2 vary significantly and it may look unfair, but you don't have to worry. Those guests who would like to eat as many sorts of cakes as possible often prefer smaller pieces. Of course, some prefer larger ones. Your mission of this problem is to write a computer program that simulates the cutting process of the cake and reports the size of each piece. Input The input is a sequence of datasets, each of which is of the following format. n w d p1 s1 ... pn sn   The first line starts with an integer n that is between 0 and 100 inclusive. It is the number of cuts to be performed. The following w and d in the same line are integers between 1 and 100 inclusive. They denote the width and depth of the cake, respectively. Assume in the sequel that the cake is placed so that w and d are the lengths in the east-west and north-south directions, respectively. Each of the following n lines specifies a single cut, cutting one and only one piece into two. pi is an integer between 1 and i inclusive and is the identification number of the piece that is the target of the i-th cut. Note that, just before the i-th cut, there exist exactly i pieces. Each piece in this stage has a unique identification number that is one of 1, 2, ..., i and is defined as follows: * The earlier a piece was born, the smaller its identification number is. * Of the two pieces born at a time by the same cut, the piece with the smaller area (looking from above) has the smaller identification number. If their areas are the same, you may define as you like the order between them, since your choice in this case has no influence on the final answer. Note that identification numbers are adjusted after each cut. si is an integer between 1 and 1000 inclusive and specifies the starting point of the i-th cut. From the northwest corner of the piece whose identification number is pi, you can reach the starting point by traveling si in the clockwise direction around the piece. You may assume that the starting point determined in this way cannot be any one of the four corners of the piece. The i-th cut surface is orthogonal to the side face on which the starting point exists. The end of the input is indicated by a line with three zeros. Output For each dataset, print in a line the areas looking from above of all the pieces that exist upon completion of the n cuts specified in the dataset. They should be in ascending order and separated by a space. When multiple pieces have the same area, print it as many times as the number of the pieces. Sample Input 3 5 6 1 18 2 19 1 2 3 4 1 1 1 2 1 3 1 0 2 5 0 0 0 Sample Output 4 4 6 16 1 1 1 1 10

This Takes the Cake
In the kingdom of Polygonia the royal family consists of the king, the queen, and the 10-year-old twins, Prince Obtuse and Prince Trisect. The twins are fiercely competitive, and on their birthday they always vie with each other for the biggest portion of the cake. The wise king and queen have devised the following way to prevent squabbles over the cake. One prince is allowed to cut the cake into two pieces, then the other prince gets to choose which of the two pieces he wants. ![](http://acm.zju.edu.cn/onlinejudge/showImage.do?name=0000%2F1806%2F1806.gif) Cakes in Polygonia are always in the shape of a convex quadrilateral (a four-sided polygon with each internal angle less than 180 degrees). Furthermore, local custom dictates that all cake cutting must be done using a straight cut that joins two vertices, or two midpoints of the sides of the cake, or a vertex and a midpoint. For instance, the following figure shows all the possible legal cuts in a typical cake. Your problem is to determine, for a number of different cakes, the best cut, i.e., the one that divides the cake into two pieces whose areas (we are disregarding the thickness of the cake) are as nearly equal as possible. For instance, given a cake whose vertices (when the cake is viewed from above) are located, in counterclockwise order, at the points (0, 1), (6, 0), (5, 2) and (2, 3), the best possible cut would divide the cake into two pieces, one with area 4.375, the other with area 5.125; the cut joins the points (1, 2) and (5:5, 1) (the midpoints of two of the sides). Input Input consists of a sequence of test cases, each consisting of four (x; y) values giving the counterclockwise traversal of the cake's vertices as viewed from directly above the cake; the final test case is followed by a line containing eight zeros. No three points will be collinear, all quadrilaterals are convex, and all coordinates will have absolute values of 10000 or less. Output For each cake, the cake number followed by the two areas, smaller first, to three decimal places of precision. Sample Input 0 1 6 0 5 2 2 3 0 0 100 0 100 100 0 100 0 0 0 0 0 0 0 0 Sample Output Cake 1: 4.375 5.125 Cake 2: 5000.000 5000.000
