[LeetCode]Surrounded Regions
Given a 2D board containing 'X' and 'O', capture all regions surrounded by 'X'. A region is captured by flipping all 'O's into 'X's in that surrounded region. For example, X X X X X O O X...

【Algorithm】回溯法与深度优先遍历的异同
1、相同点:回溯法在实现上也是遵循深度优先的,即一步一步往前探索,而不像广度优先那样,由近及远一片一片地扫。2、不同点(1)访问序深度优先遍历: 目的是“遍历”,本质是无序的。也就是说访问次序不重要,重要的是都被访问过了。可以参见题Surrounded Regions,深度优先只需要把从边界起始的....

Surrounded Regions
该题目主要考察了堆栈和深度优先搜索的知识点。在递归深度太深导致运行出错是,可以采用栈保存结果,减小递归的深度。详细代码如下:class Solution {public: stack> data; void solve(vector> &board) { if(board...
