Challenge Problems
Push your limits with advanced challenges
Consider two sorting algorithms: one with an average case of O(n log n) and another with a worst case of O(n^2). Describe a scenario where the better average case algorithm might perform worse in execution.
💡 Hint: Think about how the size of the dataset affects performance.
Given an unsorted list of numbers, develop an algorithm to find the maximum number. Analyze its worst case and average case performance.
💡 Hint: What happens if the maximum number is always at the end?
