NOTE : The files for both programs are .txt extension since my PC does not have Python installed.

Two code files have been uploaded because I couldn't run a program with command line arguments on an online compiler. The second file, that is, IvLabs ASSIGNMENT 1 (2048 GAME) is working correctly where inputs have been taken during execution

TASK : PYTHON PROGRAM TO IMPLEMENT 2048 GAME.

COMPILER USED : OnlineGDB

GAMEPLAY DESCRIPTION

The game starts with the user entering the winning number(default value 5), size of the board(default value 2048). Once entered, a game board is displayed with a 2 on the board. The user has the option to move up('W'), move down('S'), move left('A') or move right('D') given that their move causes a change in the board orientation. If not, a message is displayed stating the same and the user is expected to play their move again. While moving in any direction, change(s) can be made in the following ways - 1) All non zero numbers are shifted to the farthest possible position in the direction of motion, in order of their position. Their original postions are replaced with zeroes. 2) If 2 contiguous elements in direction of motion have the same value, the farther element in the direction of motion gets a value double of its original while the other value becomes zero. Step 1) is repeated after 2) once more to ensure all non-zero values are as shifted away in the direction of motion. For every succcessful move, a 2 is randomly placed at one position on the board which originally had a zero. The user is then asked to enter a direction of motion again following the same rules for play with a 2 being added after each successful move.

WINNING A GAME

A user wins a game when they manage to have atleast one element on the board which is equal to the winning number. In a case where the user enters a value which is not an exponent of 2, the game would be won when the user manages to play through to have a value on the board greater than the winning number.

LOSING A GAME

A user loses the game when they have no possible directions left for movement, that is, the board is full with no possible moves causing a change in the game board.
