[Leetcode] 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".

Thinking of solving problems

Two pointers, one moving forward, one moving backwards, and the other to find the vowel letters.

Implementation code
