Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Implement a tail recursive function that computes the nth Fibonacci number. Explain the role of the accumulator in your solution.

💡 Hint: Consider how to maintain the correct values with each recursive call.

Challenge 2 Hard

Create a tail recursive method to calculate power (base^exp) and analyze its efficiency.

💡 Hint: Focus on how you can reduce `exp` while retaining the multiplication result for the next call.
