Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given an unordered list of integers, use a mix of both lists and arrays to implement a simple database that allows for efficient insertions and quick searching. Outline the steps needed for both operations.

💡 Hint: Think about how a library catalog might keep entries for quick look-up but also allow for new books to be added efficiently.

Challenge 2 Hard

Design an algorithm that effectively sorts a large array and then performs a search for a specific item. Discuss the time complexity for each step of your algorithm.

💡 Hint: Consider how categories can help find items quicker, like sorting files in your computer.
