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

• Design and implement a method to reverse each word in a sentence in place. For example, if the method is called with input parameter of "I can be an   engineer", the method should update the input string object to have the value "I nac eb na   reenigne". Note that the count of white spaces between words is preserved.
• Share and explain the time and space complexities for your solution.
• At minimum, your implementation should pass the basic tests.

Note: Do not use Ruby provided functionality for .reverse and .reverse!. You may use .length.
