HDU-5031-Lines (DFS), hdu-5031-linesdfsProblem DescriptionYou play a game with your friend. he draws several lines on the paper with n × m square grids (see the left figure ). after that, he writes down the number of lines passing through every integer coordinate in a matrix (see the right figure ). The number of lines passing though coordinate (I, j) is written in cell (I, j) in the right figure. (I, j both start from 0 ). You are given the matrix

Title Link: http://www.lydsy.com:808/JudgeOnline/problem.php?id=1103The main idea: to give you a tree, just start all the tree edge Benquan are 1, and constantly change some of the edge of the right to 0, in the meantime asked you a point to the root node between the path of Benquan and.This question is similar to the apple Tree of POJ ...First DFS generates the topological order of the entire tree, DFS whe

The nearest ancestor of any two points on the tree must be the least depth of the shortest path of the two nodes.For example, in nodes 7 and 5, the shortest path is 7--4--1--5, and the smallest point on the path is node 1, with a depth of 1. Node 1 is the LCA for nodes 7 and 5.Therefore, to find any two-node LCA, we need to find the shortest path above, and then find the least depth point in the shortest path. And this is what the LCA online algorithm does.LCA Online Algorithm Description (examp

Topic: Given a length of 2^n arrangement, there are n operations, the first action is "to divide the sequence into 2^ (n-i+1) segments, each segment 2^ (i-1), and then choose Two-Segment Exchange", each operation at most once, to ask how many sequence of operations can be ordered out of the sequenceOrz DzyFirst, it is easy to see whether an operation sequence is legal and the sequence is irrelevant.So we just need to make sure that every action in an action sequence is chosen, so the contributio

Since the invention of the computer, it is natural to print the content in the computer. This is especially true after the Internet era. However, it is not easy to realize the web printing function perfectly, and it is impossible to solve this problem completely.
