Explain in brief the Backtracking approach for algorithm design. How it differs with recursion? Explain the N-Queen problem and algorithm using backtracking and analyze its time complexity.

--- Backtracking is an algorithmic design technique used to solve problems by building a solution incrementally, one step at a time, and abandoning (backtracking) a partial solution as soon as it is determined that it cannot lead to a valid complete solution. - Explore all possible candidates for...
