Option = com_onlinejudge Itemid = 8 page = show_problem problem = 679 Solution Report: Given a sequence of positive integers and a second, find the child sequence with the shortest length so that their sum is greater than or equal to S. Sequence length n Obviously, if you enumerate the start and end points, the time complexity is O (n ^ 3. How can we find the sum of a subsequence in O (1) time? We can use another array sum [I], mea

each test case, the first line contains a single integer N (1 ≤ n ≤ 10000), the numberStones placed during this set. Then follows n lines, the I-th line contains two integer x and y(1 ≤ x, y ≤ 2,000,000,000), indicates that the I-th stone was put on Row X and column Y (I startsFrom 1). The stones are given in chronological order, and it is obvious that odd-numbered stones areBlack and even-numbered ones are white.OutputFor each test case, output two integers n B and NW in one line, separated by

Question: An N * n cube, each unit lattice may be empty, or a solid color cube, giving you six views, you can see and wear. otherwise, an uppercase letter represents the color. Maximum possible volume. Analysis: A final question is like a question that describes the wit level. I am not smart enough .. I don't know how to write the question after reading the question .. Finally, I refer to the code of the white book training guide. The practice is as follows: Create a 3-dimensional array to store

Question: You have B yuan to assemble a computer. The type, quality, and price of N accessories are provided. Each type of accessories must be purchased at a total price not higher than B and the quality factor of "worst quality accessories" should be as large as possible. In this case, STL map is really useful for learning. To solve the problem of the smallest maximum value, you can use the binary method. The binary method you write will take an endless loop and learn about the binary algorith

I 've been wrong about my questions recently, orz The question is to find a string with the smallest sum of hamming values, rather than finding the smallest one from the given character. In this case, we will perform column-by-column processing. The character at the current position of the requested string should be the highest number of occurrences in the column followed by the smallest ASCII Value The Code is a little frustrated, and there are too many if statements 1 //#define LOCAL 2 #incl

First look at the effect: Wrappanel effect in the case of fixed width can not see, you can view Online Demo address: http://images.24city.com/jimmy/CustomPanel/ Some of these la s are transplanted from WPF, some are self-written, some are collected online, and may be useful in the future. Introduction: Fisheyepanel: Transplanted the "fish eye" effect of the WPF version written by foreigners. The tool bar on the Mac machine is like this. C

A few days ago did a topic, is a NIM game expansion, also can not say expand it, just say another common state. Problem Introduction: Given n heaps of stones, each stone has VI (1thinking: When the k==2, obviously degenerate into La 5059 's title, we take this as a basis to consider, we must first calculate the SG function table, and then observe the law, LRJ in the training guide is very clear, the rules of the table is also very simple, the followin

It takes a few more propositions to give you a minimum, which proves that all propositions are equivalent. The problem in a strong connected component is equal to the maximum value of a point in which the DAG is read as 0 and the out-of-0 points are
