  n皇后问题是应用回溯法的经典问题。任一行、列、对角线不能有两皇后并存，因此在判断是否合法时，可以将某一行是否有皇后、某一列是否有皇后分别用数组存起来。注意到，对于往左下右上的对角线，每个点的行号(i)和列号(j)的和相等且与别的对角线不同，因此可用数组将此对角线是否有皇后，即i+j是否为1记录下来,n*n的棋盘有2*n-1条左下到右上的对角线；对于从左上到右下的对角线也类似，每个点的行号(i)

LeetCode: N-Queens II

这道题其实我原来的思想是对的，不过不知道vector的速度要比数组慢很多，还有就是把参数放到private里也会减少运行时间。memset的时间和一个for循环是一样的，所以以后如果能确定一个数组的size并且不会改变数组大小的，就可以不用vector而用数组。多数次过 1 class Solution { 2 private: 3 int ret; 4 bool

回溯法 百度百科：回溯法（探索与回溯法）是一种选优搜索法，按选优条件向前搜索，以达到目标。但当探索到某一步时，发现原先选择并不优或达不到目标，就退回一步又一次选择，这样的走不通就退回再走的技术为回溯法，而满足回溯条件的某个状态的点称为“回溯点”。 在包括问题的全部解的解空间树中，依照深度优先搜索的策略，从根结点出发深度探索解空间树。当探索到某一结点时，要先推断该结点是否包括问题的解，假设包括，
