Solution: Reverse Vowels of a String

Explore how to reverse vowels in a string by implementing the two pointers pattern. This lesson guides you through using two pointers moving inward to swap vowels efficiently while keeping other characters intact. Understand the algorithm, its time and space complexity, and apply this pattern for effective string manipulation in coding interviews.

Statement

Given a string s, reverse only the vowels in the string and return the resulting string.

The vowels are ‘a’‘e’‘i’‘o’, and ‘u’, and they can appear in both lowercase and uppercase, potentially more than once.

Constraints:

  • 11 \leq s.length 3×105 ...
