Problem taken from LeetCode  // Problem Statement : //      You are given a string. // Write a function that takes a string as input and reverse only the vowels of a string.  // Example : //      Sample Input - 1 : //          "hello" //      Sample Output - 1 :  //          "holle"  //      Sample Input - 2 : //          "leetcode" //      Sample Output - 2 :  //          "leotcede"   class Solution {public:    string reverseVowels(string s) {        int i = 0 , j = s.size() - 1;        while(i < j) {            while(i < j &&                   (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'                   )) {                      i++;…
