 *Description:
(TicTacToe board) Write a program that randomly fills in 0s and 1s
into a TicTacToe board, prints the board, and finds the rows, columns,
or diagonals with all 0s or 1s. Use a two-dimensional array to represent
a TicTacToe board. Here is a sample run of the program:
001
001
111
All 0's on row 0
All 1's on row 2
All 1's on column 2
