Disharmony Trees 是怎么来写
Problem Description One day Sophia finds a very big square. There are n trees in the square. They are all so tall. Sophia is very interesting in them. She finds that trees maybe disharmony and the Disharmony Value between two trees is associated with two value called FAR and SHORT. The FAR is defined as the following:If we rank all these trees according to their X Coordinates in ascending order.The tree with smallest X Coordinate is ranked 1th.The trees with the same X Coordinates are ranked the same. For example,if there are 5 tree with X Coordinates 3,3,1,3,4. Then their ranks may be 2,2,1,2,5. The FAR of two trees with X Coordinate ranks D1 and D2 is defined as F = abs(D1-D2). The SHORT is defined similar to the FAR. If we rank all these trees according to their heights in ascending order，the tree with shortest height is ranked 1th.The trees with the same heights are ranked the same. For example, if there are 5 tree with heights 4,1,9,7,4. Then their ranks may be 2,1,5,4,2. The SHORT of two trees with height ranks H1 and H2 is defined as S=min(H1,H2). Two tree’s Disharmony Value is defined as F*S. So from the definition above we can see that, if two trees’s FAR is larger , the Disharmony Value is bigger. And the Disharmony value is also associated with the shorter one of the two trees. Now give you every tree’s X Coordinate and their height , Please tell Sophia the sum of every two trees’s Disharmony value among all trees. Input There are several test cases in the input For each test case, the first line contain one integer N (2 <= N <= 100,000) N represents the number of trees. Then following N lines, each line contain two integers : X, H (0 < X,H <=1,000,000,000 ), indicating the tree is located in Coordinates X and its height is H. Output For each test case output the sum of every two trees’s Disharmony value among all trees. The answer is within signed 64-bit integer. Sample Input 2 10 100 20 200 4 10 100 50 500 20 200 20 100 Sample Output 1 13
struts2.0中关于namespace到底如何指定

Struts2用Action属性接收参数报错

using Struts tags without the associated filter
<filter-mapping> <filter-name>struts2</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> 时就会出现The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location] 当我改为<url-pattern>/×</url-pattern> 时又是正确的 但因为整合了原来项目的struts1，所以只能为<url-pattern>*.action</url-pattern> 应该怎么解决这一问题 [b]问题补充：[/b] 挨，我也不想阿，但是现在必须，我学的是2,但是现在要给原来项目添加功能。所以只能这样，请问能有什么方法么 [b]问题补充：[/b] 呵呵，谢谢
Selecting Frames 框架的问题
Problem Description Given n frames of unit width, your task is to select as many frames as possible and arrange them in a line, so that none of them overlap (one enclosing another is also forbidden, but merely touching is ok). There is a restriction, though. If you select the i-th frame, you must install a small pole at Pi, then place the i-th frame surrounding that pole (the pole is so small that it can be located on the frame border). You can place the frame anywhere, as long as the pole is inside it or on its border. Input There are at most 10 test cases. Each case begins with a single integer n, the number of frames (1 <= n <= 10000). Each of the following lines contains two integers Li and Pi(1 <= Li, Pi <= 100000), the length of the i-th frame, and the position of the pole associated with that frame. No two poles will have the same position. The input ends with n = 0. Output For each test case, print the maximum number of frames you can select. Sample Input 7 5 9 2 17 6 10 3 11 2 16 4 13 5 6 0 Sample Output 5
Encode the tree 的程序的问题
Problem Description Given n labeled vertices, there are nn-2 different trees. The number is too large, but Wiskey want to use a way to encode the tree that make a unique sequence associated with the labeled tree. Follow this way: 1.Select the vertex u which degree is 1 and the labeled number is the minimum. Example, u = 4. 2.Select the neighbor v of u, exists the edge which u to v. Example, v = 1. 3.Delete the edge from the tree. Example, the edge of 1-4 will be deleting. 4.Repeat the first step, until only two vertices left. 5.We will get the sequence {u1, u2… un-2} and {v1, v2… vn-2}. Now, give you the v sequence, tell me the u sequence. Input First line will contain one integer mean how many cases will follow by. N represents the number of vertices, and the label start from 1. (3 <= N <= 100). The next N-2 numbers mean the v sequence. Output Output the u sequence in one line, separate by a blank space. Sample Input 1 8 1 2 1 3 3 5 Sample Output 4 6 2 1 7 3

FIB Query 查询问题
Problem Description We all know the definition of Fibonacci series: fib[i]=fib[i-1]+fib[i-2],fib[1]=1,fib[2]=1.And we define another series P associated with the Fibonacci series: P[i]=fib[4*i-1].Now we will give several queries about P:give two integers L,R, and calculate ∑P[i](L <= i <= R). Input There is only one test case. The first line contains single integer Q – the number of queries. (Q<=10^4) Each line next will contain two integer L, R. (1<=L<=R<=10^12) Output For each query output one line. Due to the final answer would be so large, please output the answer mod 1000000007. Sample Input 2 1 300 2 400 Sample Output 838985007 352105429

Essay Scoring System 程序代码
Problem Description Professor Binns has finally got tired of scoring essays himself and implemented an automatic essay scoring system to help him screen the numerous essays. Strongly against such an idea, you decided to generate a meaningless essay which can get high mark in his system to prove that his system does not work at all. You've obtained the rules used by Binns's system to score the essay, they're as follows: a) The word in the essay must be from a particular set of words. If not, the essay will receive a score zero and is automatically rejected. b) Every word in the specified set has a positive integer associated with it, indicating the score the submitter will get for using that word once. c) A word can be used in several different ways; for example, in English, the word “word” can be used as both a noun and a verb. Every occurrence of specific patterns (like verb – adjective – noun) will earn the submitter a particular score. In particular, it is allowed for a word to be interpreted in different ways in different patterns. You're interested in generating an essay of a specified length with maximum possible score. Input There are multiple test cases in the input file. Each test case starts with three integers N, M and K, (1 <= N <= 100, 0 <= M <= 8, 0 <= K <= 6), the length of the essay to generate, the number of words in the dictionary and the number of patterns, respectively. The following M lines describe the words in the dictionary; each line consists of two integers, Wi, and Ti, (0 <= Wi <= 2000, 1 <= Ti <= 5), representing the score submitter gets every time he/she uses the word, and the number of ways the word can be used. The next part of the input describes the patterns. Each of the K lines describes one pattern, beginning with two integers, Wi, and Ci, (0 <= Wi <= 2000, 1 <= Ci <= 6), indicating the score one can get every time the pattern is used, and the number of consecutive parts in the pattern; followed by Ci integers describing the language parts in the pattern. It is guaranteed that the total number of ways to use a word does not exceed 5; furthermore, the total number of parts contained in all patterns (sum of all Cis) will not exceed 25. There is a blank line after each test case. Input ends with End-of-File. Output For every test case, you should output one integer on a separate line, the maximum score one can get, in the format as indicated in the sample output. Sample Input 2 3 2 4 3 0 1 2 5 2 2 3 1 2 0 4 1 2 1 3 10 2 4 2 2 3 2 4 3 0 1 2 5 2 2 3 1 2 0 4 1 2 1 3 2 2 4 2 Sample Output Case 1: 16 Case 2: 10
