Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have two sorted lists of numbers ranging from 1 to 100. One has only odd numbers, while the other has even numbers. Write a Python function that merges these two lists and handles any potential index errors effectively.

💡 Hint: Consider using two-pointer technique while maintaining valid index checks.

Challenge 2 Hard

Consider a case where the first list is significantly longer than the second and includes repeated numbers. Discuss how this affects the merging function's performance. What would you adjust in your code to optimize it?

💡 Hint: How can you reduce the number of checks when one list runs out?
