[leetcode]N-Queens II

一开始不明白为什么有这么一道几乎完全一样的，但把I的改一下超时了，所以要优化一下。经搜索，发现可以这样优化：使用col[i]表示第i行Q所在的列，那么，判断斜线是否满足就可以用abs(k-i)== abs(col[k]-j)，注意这里k要小于i，因为后面的行没有放Q，而默认初始化时0列放Q，就会错误。 public class Solution { private int ans;

N皇后，回溯法。然后想想怎么写呢？一开始想两个循环，但那就成了完全遍历，回溯法是可以剪枝一部分的。先想什么作为阶段，可以选第i行的Q做为回溯的阶段，选好某行后向选下一行的，用递归。 public class Solution { private ArrayList<String[]> ans = new ArrayList<String[]>();
