Regarding queen permutation

Mam/Sir Can you tell me how the backtracking is performed at q0 level how it will gone back to q0

Hi @saurabhananta,
The backtracking is performed when we remove the queen from a slot. The process of removing is called to backtrack … That when the queen was at lets say second position then removing it from that position and putting it at any other position.
