String Reverse

In this assignment, you'll design and implement one of the string manipulation functions. Remember that a string is an array of characters. Algorithms that worked on array data structure will work on strings as well.

Exercise

• Design and implement a method to reverse a string in place. The method takes the string to be reversed as input parameter.
• Above the method, elaborate the comment to share the time and space complexity of your method.
  • Your solution should optimize the space complexity as much as possible. In other words, do not use any more space than needed.
  • If you explain the complexity in terms of n, be sure to explain what n stands for.
• For example, if the method is called with input parameter of "Lovelace", the method should update the input string object to have the value "ecalevoL".
• Notes:
  • Do not use Ruby provided functionality for .reverse and .reverse!.
  • You may use .length method available in the String class.
  • You may access a character at a given index or set the value at a given index.
