Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider an algorithm that consists of nested loops where the outer loop runs n times and the inner loop runs n times as well. Calculate the time complexity, and explain the reasoning behind it.

💡 Hint: Think about how many times does each operation in the inner loop get executed based on the outer loop.

Challenge 2 Hard

You have two algorithms: one runs in O(n log n) time and the other in O(n^2) time. Explain in what scenario one would be preferable over the other when handling large datasets.

💡 Hint: Consider the scalability of each algorithm as data grows.
