/*Problem statement
Functions - Take this coding challenge to test your coding skills to
-define a function
-pass arguments by value to a function
-pass arguments by reference to a function
This coding challenge is organized in the following way:
First line of input reads an integer to select the coding challenge:
-Reading value '1' selects the coding-challenge 1 ( tests the ability to define a function and pass arguments by value.)
-Reading value '2' selects the coding challenge 2 (tests the ability to pass arguments by reference to a function)
Coding Challenge -1
Define a function named "Maximum" that accepts two integers (pass by value) as arguments and returns the greatest of the two arguments.
Coding Challenge -2
Define a function named "Swap" that accepts two integers (pass by reference) as arguments and swaps their value.
Detailed explanation ( Input/output format, Notes, Images )
Sample Input 1:
1
2 3
Sample Output 1:
3
Explanation of sample input 1 :
The maximum of 2 and 3 is 3.
Sample Input 2:
2
4 5
Sample Output 2:
5 4
Explanation of sample input 2 :
The values 4 and 5 are swapped.
Expected time complexity :
The expected time complexity is O(1).
