What is the backtracking technique in algorithms?

Backtracking is a problem-solving technique used in algorithms to find solutions by exploring all possible options.

Can you give me an example of where backtracking is used?

Sure! A common example is solving puzzles like Sudoku, where you try different numbers in empty cells.

How does backtracking differ from brute force?

Backtracking is more efficient than brute force as it eliminates paths that won't lead to a solution, reducing unnecessary checks.

Are there any specific algorithms that use backtracking?

Yes, algorithms like the N-Queens problem, the Hamiltonian path, and the subset-sum problem utilize backtracking.
