Auxiliary space complexity: O(N) where N is the length of the string. Your result must be a string. While string enums dont have auto-incrementing behavior, string enums have the benefit that they serialize well. Step 2: reverse () reverse method reverses an array in a way that the first element becomes last and the last one becomes first but it only works on the array.
