leetcode 221. Maximal Square leetcode 221. Maximal Square 给定一个元素只有0或1的matrix,寻找其中由1组成的最大正方形的面积。 采用动态规划解题。 dp[i][j]表示以i,j为右下角的值为1...-1], dp[i-1][j], dp[i][j-1]) + 1 可以在脑海里想象一下,大概是这种情形: 小A点菜 。他想知道...
leetcode64:Minimum Path Sum 思路:跟之前走方格的题差不多,只是状态转移方程稍微改变一下。dp[i][j] = Math.min(dp[i - 1][j], dp[i][j - 1]) + grid[i][j];。 代码: 输出: 01串 --- 递推 这是一个符合斐波纳契数列的dp问题,动态转移方程:dp[i]=dp[i-1]+dp[i-2]; 解释:长度...
In a valid string, ignoring '1's, we see that '0' and '2' must "alternate", starting and ending with '0' (e.g. if you remove '1's in a valid string, then the sequence must look something like "020202020"). Furthermore, it is easy to see that any string that satisfies this...
