345. Reverse Vowels of a String
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".
思路:双指针首位夹逼,转成array来swap相对应的vowel,最后输出新的string

public class Solution { public String reverseVowels(String s) { ArrayList<Character> check=new ArrayList<Character>(); check.add(‘a‘); check.add(‘e‘); check.add(‘i‘); check.add(‘o‘); check.add(‘u‘); check.add(‘A‘); check.add(‘E‘); check.add(‘I‘); check.add(‘O‘); check.add(‘U‘); char[] transfer=s.toCharArray(); int i=0; int j=transfer.length-1; while(i<j) { if(!check.contains(transfer[i])) { i++; continue; } if(!check.contains(transfer[j])) { j--; continue; } char temp=transfer[i]; transfer[i]=transfer[j]; transfer[j]=temp; i++; j--; } return new String(transfer);}}
