题目: Given two words word1 and word2, find the minimum number of steps required to convert word1 to word2. (each operation is counted as 1 step.) You have the following 3 operations permitted on a word: a) Insert a characterb) Delete a characterc) Rep…
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. 给定两个字符串,判断他们是否是一步变换得到的. 在这里需要注意几点: 1.不等于1的变换都要返回false(包括变换次数等于0). 2.还有很多细节需要注意. 方法如下: 1.直接判断:1)如果差值大于1,直接返回false. 2)如果长度相同,那么依次判断,是否只有一个字母不一样. 3)如果不一样,那么看是否是只是多出了一个字母. p…
