Hey @anubhavb11,

Mistakes in your code:

  1. Question reads: We are asked to place N number of Knights in it.
    There is no condition in your code for this while it is present in the code i have shared.

  2. You are not counting the total number of possible placements which is also the requirement of the question.

  3. You have to check for the following 8 moves:
    {-1,-2}, {-2,-1}, {-2, 1}, {-1, 2}, {1, 2}, {2, 1}, {2, -1}, {1, -2}
    while you are checking for only 4 moves.

Correct these.
