 Simple Scheduling Problem 代码编辑的思想

Problem Description
Team YouAreSoStrong meet a very boring problem. They have to schedule n jobs on m machines. Each job needs exactly one unit time on one machine. At first, YouAreSoStrong thought ceil(n/m) units of time is enough. Soon, they find out there exist some ordering constraints between jobs. This is reasonable. For example, you have to complete "hand in hand" before you can "hug". And only after you've done "hug", can you "kiss". It's guaranteed that following 3 conditions are satisfied.
1. one job can only be relied by at most one job.
2. one job may rely more than one job.
3.There is no circular dependency. Such as a relies on b, and b relies on a.
YouAreSoStrong thought for a long time, but do not have a clue. Can you help them?Input
First line contains one integer T, indicates the number of test cases. For each case, the first line contains 3 integers : n, e, m, denotes number of jobs, number of ordering constraints, number of machines separately.

20190613Problem Description Li Zhixiang have already been in “Friendship” oceangoing freighter for three months. The excitement has gradually disappeared. He stands on the board, holding the railing and watching the dazzling ocean in the sun silently. Day after day, the same scenery is monotonous and tasteless, even the merry seagulls following the freighter cannot arouse his interest. Hearing the footsteps behind, he turns back to see the old captain is coming towards him. The captain has understood his idea, however, he starts a new topic with the young man. “Do you know how far our voyage is?” The captain asks. Li Zhixiang feels ashamed because he can not answer. Then the captain says with a smile, “5050 miles. Do you still remember the story of 5050?” This time the young man really blushes. The old captain continues saying:” You definitely know the story of 5050. When the German mathematician, “the prince of mathematicians”, Gauss was 10 years old …” Young man remembers this story and goes on to tell, “ When Gauss was 10 years old, he could add a list of integers from 1 to 100 in a few seconds, which shocked the teachers.” The old captain adds, “Gauss has many other stories like this. When he entered the university at the age of 17, he was able to construct heptadecagon by compass and straightedge. His university teachers were also impressed by his ability. Not only could college graduate students fail to do it, but also they felt hard to understand Gauss’s constructing process.” At this time, vicecaptain greets the old captain. The old captain says to Li Zhixiang: “Come over to my office tonight, let’s continue the conversation.” It is still calm and tranquil in the evening. The freighter travels smoothly on the sea in the silver moonlight. The captain tells the young man the following words. Among the mathematicians through the ages, there are three greatest mathematicians: Archimedes, Newton and Gauss. Most of Gauss’s mathematical achievements are difficult to understand. Nevertheless, there are some comparatively easy. For instance, when it comes to solving multivariate system of linear equations, there is a solution called “Gauss Elimination”. In the navigation business, many problems can be solved by “Gauss elimination”. If you are interested in it, I will show you a simple question. Try it.” Input There are several test cases. In the first line of each case, a number n indicates that there are n equations. The following n lines, each line has n+1 numbers, ai1,ai2,ai3…..ain, bi(1<= i <=n), these numbers indicate the coefficients of systems of the equations. ai1*x1+ai2*x2+......ain*xn=bi. Input is terminated by the end of file. Output For each given systems of equations, if there are solutions, output n solutions in the order of appearance in the equations（n<=100）, each solution number is in one line. If solution is not integer, show it in fraction. If no solution, output “No solution.” Leave a blank line after each case. Sample Input 2 1000000000000000000000000 1000000000000000000000000 1000000000000000000000000 1000000000000000000000000 1000000000000000000000000 0 1 0 4 Sample Output 1/2 1/2 No solution.
Range 区间的问题_course
20200416Problem Description Some automobiles display the estimated driving range, that is, the distance you can expect to drive it (without adding fuel) before running out of fuel. Here is how it works: periodically, the vehicle's computer records the odometer reading and the weight of fuel in the fuel tank. From this data, the fuel consumption over a certain distance can be computed. From the fuel consumption and the most recent measurement of fuel tank contents (which we assume is current for all practical purposes), the range can be calculated. Intervals over which the quantity of fuel increased (fuel was added to the tank) will not be used in the computations. For example, in the first problem instance of the sample input, the interval where the fuel weight increased from 29.9 kilograms to 34.2 kilograms will not be used. In this example, 16.3 kilograms of fuel were consumed over a distance of 228.6 kilometers. Therefore, the most recently measured fuel contents of 31.2 kilograms will enable you to drive another 438 kilometers (rounded to the nearest integer). The input will always contain at least one interval (two consecutive lines of input) where no fuel was added to the tank. Input The input contains data for a number of problem instances. Each problem instance consists of three or more (odometer reading, fuel weight) pairs, one pair per line. Distances are measured in kilometers and fuel weight in kilograms. All input numbers will be given to one decimal place. The end of each problem instance will be signaled by a (0.0, 0.0) pair. The last problem instance will be followed by a (1.0, 1.0) pair. Output For each problem instance, print the range, rounded to the nearest integer. Sample Input 18400.5 43.2 18440.4 40.4 18482.7 37.0 18540.2 33.1 18585.3 29.9 18620.8 34.2 18664.6 31.2 0.0 0.0 18400.5 43.2 18440.4 40.4 18482.7 37.0 18540.2 33.1 18585.3 29.9 0.0 0.0 1.0 1.0 Sample Output 438 415

20190810Problem Description Using a sheet of paper and scissors, you can cut out two faces to form a cylinder in the following way: 1. Cut the paper horizontally (parallel to the shorter side) to get two rectangular parts. 2. From the first part, cut out a circle of maximum radius. The circle will form the bottom of the cylinder. 3. Roll the second part up in such a way that it has a perimeter of equal length with the circle's circumference, and attach one end of the roll to the circle. Note that the roll may have some overlapping parts in order to get the required length of the perimeter. Given the dimensions of the sheet of paper, can you calculate the biggest possible volume of a cylinder which can be constructed using the procedure described above? Input The input consists of several test cases. Each test case consists of two numbers w and h (1 ≤ w ≤ h ≤ 100), which indicate the width and height of the sheet of paper. The last test case is followed by a line containing two zeros. Output For each test case, print one line with the biggest possible volume of the cylinder. Round this number to 3 places after the decimal point. Sample Input 10 10 10 50 10 30 0 0 Sample Output 54.247 785.398 412.095

数字的多次的迭代的算法的问题的解决的方式，用的是C程序的语言的编写的过程怎么做_course
20190409Problem Description For any positive integer n, we define function F(n) and XEN(n). For a collection S(n)={1,2,...,2n}, we select some numbers from it. For a selection, if each selected number could not be divided exactly by any other number in this selection, we will call the selection good selection. Further, we call a good selection best selection if the selection has more elements than any other good selection from S(n). We define F(n) the number of elements in the best selection from S(n). For example, n=2, F(n)=2. From the collection {1,2,3,4}, we can make good selection just like {2,3} or {3,4}, but we can't make any larger selection. So F(2) = 2. Then we pay attention to XEN(n). For every S(n), there are always some numbers could not be selected to make up any best selection. For instance, when n=2, 1 is always could not be chosen. What's more, for every S(n), there is a number k which satisfies that all the number, from 0 to k, are always could not be chosen. Now we let XEN(n)=k: n=2, F(n)=2, XEN(2)=1; n=4, F(n)=4, XEN(4)=1. You should write a program to calculate the value of F(n) and XEN(n) with a given number n. Input Your program is to read from standard input. There are multiple cases. For each case, one integer n (1 ≤ n ≤ 10^7) in a line. Output Output two integers with one space between them in one line per case. Sample Input 2 4 Sample Output 2 1 4 1
SCV集合的查询和数组操作的问题，采用C技术语言_course
20190123Problem Description StarCraft 2 (SC2) is a famous game. More and more people fall in love with this game. As a crazy fan of SC2, Ahua (flower fairy) play it day and night. Recently, he found that the most important part of being a top player of SC2 is economic development, which means you should get as much mine as possible by training SCVs (space construction vehicle) to collect mine. Train a SCV at ith second costs Ci units of mine. After training, this SCV can collect Di units of mine each second. Training a SCV needs one second of time. Based on that, he composes a formula to evaluate the development in a time span from xth second to yth second. Assume at xth second, Ahua has no SCV and mine. He trains one SCV at each second during xth second and yth second (the mount of mine can be negative, so that he always can train SCV). Each SCV will collect some amount of mines for Ahua in each second after it was trained. At ith second Ahua has Mi units of mine in total. The development value is defined as sum(Mi) (x ≤ i ≤ y). Now he asks you to help him calculate the development value. To make it more interesting, Ahua can apply following operations: Cost x y z: the cost of training a SCV between xth second to yth second will increase by z units of mine. i.e. Ci for x ≤ i ≤ y will increase by z. Collect x y z: each SCV trained between xth second and yth second can collect z more mines every second after it has been trained. i.e. Di for x ≤ i ≤ y will increase by z. Query x y: output the development value between xth second and yth second. Input First line of the input is a single integer T (T ≤ 10), indicates there are T test cases. For each test case, the first line is an integer N (1 ≤ N ≤ 100000), means the maximum time you should deal with. Following N lines, each contain two integers Ci and Di (0 ≤ Ci, Di ≤ 100000), the cost and collect speed of SCV training in ith second initially as described above. The next line is an integer Q (1 ≤ Q ≤ 10000), the number of operations you should deal with. Then Q lines followed, each line will be “Cost x y z”, "Collect x y z” or “Query x y”. 1 ≤ x ≤ y ≤ N, 0 ≤ z ≤ 100000 Output For each test case, first output “Case k: “ in a single line, k is the number of the test case, from 1 to T. Then for each "Q x y", you should output a single line contains the answer mod 20110911. Sample Input 1 5 1 3 2 3 3 1 2 2 3 3 5 Query 1 3 Cost 2 2 1 Query 1 3 Collect 1 1 5 Query 1 3 Sample Output Case 1: 2 0 15
