Modify all the code files such that they contain:

• @breif: A short description of problem
• Function description in the form of:

   /*
  * Function Name:<Function Name>
  * Input: <Inputs (or Parameters) list with description if any>
  * Output: <Return value with description if any>
  * Logic: <Description of the function performed and the logic used
  * in the function>
  * Example Call: <Example of how to call this function>
  */
  

• Analysis: Time complexity of the code
