Given two strings S and T, determine if they are both one edit distance apart. 这道题是之前那道Edit Distance的拓展,然而这道题并没有那道题难,这道题只让我们判断两个字符串的编辑距离是否为1,那么我们只需分下列三种情况来考虑就行了: 1. 两个字符串的长度之差大于1,那么直接返回False 2. 两个字符串的长度之差等于1,那么长的那个字符串去掉一个字符,剩下的应该和短的字符串相同 3. 两个字符串的长度之…

Given two strings S and T, determine if they are both one edit distance apart. 分析:https://segmentfault.com/a/1190000003906621 虽然我们可以用Edit Distance的解法,看distance是否为1,但Leetcode中会超时.这里我们可以利用只有一个不同的特点在O(N)时间内完成.如果两个字符串只有一个编辑距离,则只有两种情况: 两个字符串一样长的时候,说明有一个替换…
