Given two strings s and t, determine if they are both one edit distance apart. Note: There are 3 possiblities to satisify one edit distance apart: Insert a character into s to get t Delete a character from s to get t Replace a character of s to get t…

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…

题目: Given two strings S and T, determine if they are both one edit distance apart. 链接: http://leetcode.com/problems/one-edit-distance/ 题解: 求两个字符串是否只有1个Edit Distance. 看着这道题又想起了Edit Distance那道.不过这道题不需要用DP,只用设一个boolean变量hasEdited来逐字符判断就可以了.写法大都借鉴了曹神的代码.…

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…

Difficulty: Medium  More:[目录]LeetCode Java实现 Description Given two strings S and T, determine if they are both one edit distance apart. Intuition 同时遍历比较S和T的字符,直至遇到不同的字符:如果S和T的字符个数相同时,跳过不同的那个字符,继续遍历:如果S和T的字符个数相差为1时,跳过较长的字符串的当天字符,继续遍历.如果剩下的字符都相等,那么返回tr…

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 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) Replace…
