Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given an array of integers, implement insertion sort without using loops. Instead, use recursion.

💡 Hint: Focus on breaking down the problem, using base cases effectively.

Challenge 2 Hard

Analyze how insertion sort can be adapted for sorting a reverse-sorted array. What would the performance be like?

💡 Hint: Consider worst-case scenarios and draw parallels to sorted use cases.
