Boards Consider the following depiction of a tic-tac-toe board This board is represented by the 60 character C string: If we consider the Xs to be represented by 2s and the Os by 1s and the blank spaces by Os. We can encode the board above by the base-3 number 2100000003) which is equal to 15,309 Write a function that converts the C string board representation to a base-3 string void boardtob3( char b3(10], char board 60] and a function that converts the base-3 string representation back into a C string board void boardfromb3 char board[60], char b3[10]
