Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a set of elements {1, 2, 3, 4, 5}, illustrate the union-find operations after performing unions (1,2) and (3,4). Followed by a union (2,4). Construct the final structure.

💡 Hint: Start by visualizing the connections after each union.

Challenge 2 Hard

Explain how amortized analysis is done for the union-find structure. What can we conclude about time complexities per operation?

💡 Hint: Consider approximating over multiple sequences rather than single operations.
