Write a program for a matchstick game being played between the computer and a user. Your program should ensue that the computer always wins. Rules for the games are as follows :

• There are 21 matchsticks
• The computer asks the player to pick 1,2,3 or 4 matchsticks
• After the person picks the computer does its picking
• Whoever is forced to pick the last matchstick loses the game.

Hint: (The computer would pick the matchstick so that th total is 5, so if the user picks 1 the computer picks 4, if the user picks 2 compute picks 3 and so forth)
