Given a Union-Find structure with n elements and m union operations, describe the expected time complexity for m find operations, including the impact of path compression.
💡 Hint: Consider the efficiency gained by repeatedly flattening the tree.
Imagine you have a scenario where many union operations result in a deep tree structure. Describe how using path compression can alter the time complexity of subsequent find operations.
💡 Hint: Think about what happens to the height of the tree after each find.
