Reverse a string. The input string is given as an array of caracters char[]. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. Example 1: program input: hello method input:['h','e','l','l','o'] method result: ['o','l','l','e','h'] program output: hello reversed is olleh Example 2: program input: Hannah method input: ['H','a','n','n','a','h'] method result: ['h','a','n','n','a','H'] program output: Hannah reversed is hannaH //Please write the method reverseString. Everything else //should not be changed.
