Simulation of the game of Snake in 2D array assignment help

This assignment requires us to write a program that creates a 2D array, that represents a game area where a snake moves until it collides with itself. The program created by our array assignment helpers reads in the number of moves, and the direction and distance for each move. If the snake hits an obstacle or itself then you end the simulation.
