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…

Problem: Given two strings S and T, determine if they are both one edit distance apart. General Analysis: This problem is not hard. However, to write out more efficient and elegant solution, we need to dive more deep to understand the logic behind it…
