Given s = "hello", return "holle".
Example 2:
Given s = "leetcode", return "leotcede"
static public string ReverseVowels(string s) {Stack<char> vowelsStack = new Stack<char>();for (int i = 0; i < s.Length; i++) {char c = s[i];if (c == ‘a‘ || c == ‘e‘ || c == ‘i‘ || c == ‘o‘ || c == ‘u‘ ||c == ‘A‘ || c == ‘E‘ || c == ‘I‘ || c == ‘O‘ || c == ‘U‘) {vowelsStack.Push(c);}}string rsult = "";for (int i = 0; i < s.Length; i++) {char c = s[i];if (c == ‘a‘ || c == ‘e‘ || c == ‘i‘ || c == ‘o‘ || c == ‘u‘ ||c == ‘A‘ || c == ‘E‘ || c == ‘I‘ || c == ‘O‘ || c == ‘U‘) {rsult += vowelsStack.Pop();} else {rsult += c;}}return rsult;}
