4 cards from this section. Quick, good the night before a test.
What are the three key operations of a union-find data structure?
Think about what operations track and manage sets.
Explain what path compression does during a find operation.
Consider how this affects subsequent operations.
What does path compression primarily improve in the union-find data structure?
Think about what operation is directly aided by reducing paths in the data structure.
True or False: With path compression, the union operation always takes constant time.
Reflect on how merging trees might work.
If a union-find structure has 1000 nodes, and 900 union operations are executed with path compression, how would you describe the final tree structure?
Visualize how multiple unions lead to various branches merging.
In a scenario where elements are added incrementally to the union-find structure, come up with a strategy to apply path compression effectively.
Consider how paths change with every operation.
