Objective: Write a script that allows two people to play tic-tac-toe. The script should allow each player to take sequential turns and to interactively enter their choice of position at the command line on each turn. For each turn, the script should output the set-up of the board. Note, you dont have to use x and o as the symbol of each player. Note, the main body of this code should be able to be written in less than 30 lines. (Code in R) Use functions, loops, arrays, readlines, if else statements
