Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Write a recursive function to compute the nth Fibonacci number, given n. Optimize it using memoization to avoid redundant calculations.

💡 Hint: Think of storing results in a dictionary to reduce computation time.

Challenge 2 Hard

Implement a recursive function for solving the N-Queens puzzle; you need to place n queens on an n x n chessboard without attacking each other.

💡 Hint: Consider how to place one queen at a time and retract if a conflict arises.
