What are some examples of backtracking algorithms?

Backtracking algorithms are used to solve problems incrementally, trying partial solutions and abandoning them if they fail. Examples include the N-Queens problem, Sudoku solver, and the Hamiltonian path problem.

Can you explain how the N-Queens problem works?

Sure! The N-Queens problem involves placing N queens on an N×N chessboard so that no two queens threaten each other. A backtracking algorithm tries to place queens one row at a time and backtracks when it finds a conflict.

What is the time complexity of backtracking algorithms?

The time complexity of backtracking algorithms can vary widely depending on the problem. For example, the N-Queens problem has a time complexity of O(N!), while other problems may have different complexities.

Are there any real-world applications of backtracking?

Yes, backtracking is used in various fields such as puzzle solving, game development, and optimization problems, like scheduling.
