/*
A game of Tic Tac Toe has just been completed. Write a function that prints whether X's or O's have won. The game board is passed in as an array of integers in row-column order. The Number 2 represents X and the number 1 represents O. A zero represents that the space is empty.

For example the gameboard below would be represented as int* gameboard = [2,0,1,1,1,0,2,2,2]

x-o

oo-
