class Solution {

   public void reverseString(char[] s) {
        
        int length = s.length;
        
        if (length <= 1) {
            return;
        }
        
        for (int start = 0,end = s.length - 1; start < end; start++, end--) {
            char c = s[end];
            s[end] = s[start];
            s[start] = c;
        }

    }
