Reverse Vowels of a String 只反转字符串元音字符 Write a function that takes a string as input and reverse only the vowels of a string. Example 1: Given s = “hello”, return “holle”. Example 2: Given s = “leetcode”...leetcode 345. Reverse Vowels of a String 反转字符串中的...
Leetcode之Reverse Vowels of a String 问题 很简单,就是元音字母交换,采用两个指针,一个start指向前面的元音字母,另外一个end指向后面的元音字母,如果start指向的不是元音字母,我们直接start++,直到指向元音字母为止;同理,end也是一样,从右往左,直到它指向元音字母,现在我们就可以交换了,将start和end指向的字符交换。
Leetcode之Reverse Vowels of a String 问题 问题描述: Write a function that takes a string as input and reverse only the vowels of a string. Note: The vowels does not include the letter "y". 示例一: Given s = "hello", return "......
Write a function that takes a string as input and reverse only the vowels of a string. Example 1: Given s = "hello", return "holle". Example 2: Given s = "leetcode", return "leotcede". 这道题让我们翻转字符串中的元音字母,元音字母有五个a,e,i,o,u,需要注意的是大写的也算,所以总...
#Leetcode# 345. Reverse Vowels of a String https://leetcode.com/problems/reverse-vowels-of-a-string/ Write a function that takes a string as input and reverse only the vowels of a string. Example 1: Example 2: Note: The vowels does not ......
Given s = “leetcode”, return “leotcede”. Note: The vowels does not include the letter “y”. 这道题考察的是反转一个字符串中的所有的元音字符,使用双指针,然后交换即可。 代码如下: /* * 双向指针,一次遍历即可,交换所有的元音字符
