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

BFS, breadth First search, one layer to traverse the diagram, it is called breadth first. Implementation method: Queue. DFS, Depth-first search, wall-to-back traversal, called depth first. Implementation method: Recursive (Stack). Both of these traversal methods are the basic way to access the graph. If the comparison of the tree, BFS corresponding to the level of traversal, DFS corresponding to three basic

https://vjudge.net/problem/POJ-3009Finish this question, feel oneself to the DFS understanding should be profound again.1. In general, the minimum number of steps are used BFS, but this problem because the status record is very troublesome, so you can use DFS.2. In the use of DFS, MP when a global variable, for the equality of the way, every way after the end of
