Date Game

// THE GAME IS PLAYED BY USER Vs CPU

//    RULES OF THE GAME

// 1. EACH TURN A CHANCE TO CHANGE EITHER MONTH OR DATE BUT NOT "BOTH".

// 2. WHO EVER REACHES THE FINAL DESTINATION (i.e, DEC 31) IN A CALENDER WILL WON THE GAME.

// 3. THERE IS NO WAY TO GO BACK FROM A GIVEN POSITION (since always TIME moves in
// forward or positive direction).

// 4. A LEAP YEAR IS CONSIDERED AS STANDARD REFERANCE (SO FEB HAS 29 DAYS).
