Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given that an algorithm has a time complexity of O(n^2), estimate the largest input size it can handle if you require it to run in under 5 seconds with computational power estimated at 10^7 operations per second.

💡 Hint: Remember to set up the equation based on complexity and expected execution time.

Challenge 2 Hard

Propose an efficient algorithm for searching through a sorted list and describe its efficiency with respect to Big O notation.

💡 Hint: Think about how the algorithm narrows down the search space.
