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".
题意：将一个字符串中a,e,i,o,u收尾互换位置，返回。
class Solution {
public:
string reverseVowels(string s) {
int len = s.length();
char temp;
for(int i = 0, j = len - 1; i < j; i++) {
if(s[i] == ‘a‘ || s[i] == ‘e‘ || s[i] == ‘i‘ || s[i] == ‘o‘ || s[i] == ‘u‘ ||s[i] == ‘A‘ || s[i] == ‘E‘ || s[i] == ‘I‘ || s[i] == ‘O‘ || s[i] == ‘U‘) {
for(j; j > i; j--)
if(s[j] == ‘a‘ || s[j] == ‘e‘ || s[j] == ‘i‘ || s[j] == ‘o‘ || s[j] == ‘u‘ ||s[j] == ‘A‘ || s[j] == ‘E‘ || s[j] == ‘I‘ || s[j] == ‘O‘ || s[j] == ‘U‘) {
temp = s[i];
s[i] = s[j];
s[j] = temp;
j--;
break;
}
}
}
return s;
}
};
