题解
当左指针和右指针匹配的字符串都为元音时匹配即可。
方法一:双指针
/**
* @param {string} s
* @return {string}
*/
var reverseVowels = function(s) {
let vowels = ['a', 'A', 'e', 'E', 'i', 'I', 'o', 'O', 'u', 'U'];
s = s.split('');
let p1 = 0;
let p2 = s.length - 1;
while (p1 < p2) {
if (vowels.includes(s[p1]) && vowels.includes(s[p2])) {
[s[p1], s[p2]] = [s[p2], s[p1]];
p1++;
p2--;
} else if (!vowels.includes(s[p1])) {
p1++;
} else if (!vowels.includes(s[p2])) {
p2--;
}
}
return s.join('');
};
