62. Unique Paths class Solution { public: int uniquePaths(int m, int n) { || n <= ) ; vector<vector<int> > dp(m,vector<int>(n)); dp[][] = ; ;i < m;i++) dp[i][] = ; ;i < n;i++) dp[][i] = ; ;i < m;i++){ ;j < n;j++){ dp[i][j]…

一.题目说明 题目62. Unique Paths,在一个m*n矩阵中,求从左上角Start到右下角Finish所有路径.其中每次只能向下.向右移动.难度是Medium! 二.我的解答 这个题目读读题目,理解后不难.定义一个dp[m][n],初始化最后一列为1,最后一行为1,然后循环计算到dp[0][0]就可以了. 代码如下: class Solution{ public: int uniquePaths(int m,int n){ vector<vector<int>> dp(m…
