This short tutorial will walk you through the concept of backtracking.

• Backtracking is a technique based on algorithm to solve problem. It uses recursive calling to find the solution by building a solution step by step increasing values with time

• It removes the solutions that doesn't give rise to the solution of the problem based on the constraints given to solve the problem.

• Given a chessboard of size N*N

• Place N queens on this chessboard such that no two queens attack each other.

I hope you have just as much fun playing around with this visualization tool as I had building it!
