Add Tictactoe program in Backtracking

[lakshyabatman]

This is a(n):

• New algorithm
• Update to an existing algorithm
• Error
• Proposal to the Repository

Details:

I guess program TicTacToe solver would be great to add in backtracking section, the algorithms follow backtracking and check all possible on a given tic-tac-toe matrix and prints best possible move.
I'll be sending PR fro c++ one with readme according to another folders.
