Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a sequence of union operations, illustrate how the data structure looks after each operation. Describe what happens to the find operations for the involved elements.

💡 Hint: Use a diagram to represent the sequence and changes.

Challenge 2 Hard

Suppose you implement path compression in the union-find structure. Analyze the implications of this on the time complexity of find operations across multiple sequences.

💡 Hint: Sketch out how the path updates during the process.
