Question 1

What does the 'find' operation accomplish in a Union-Find structure?

  • Merges two components
  • Checks the component of an element
  • Counts the number of elements

💡 Hint: Think about its purpose in relation to set membership.

Question 2

Amortized analysis helps in determining the average time per operation across multiple operations.

  • True
  • False

💡 Hint: Ponder on the consequences of averaging time over many executions.

Challenge Problems

Push your limits with challenges.

Question 1

Given a set of seven elements with the following union operations: (1, 2), (2, 3), (4, 5), (5, 6), (1, 5). Determine the final components formed.

💡 Hint: Draw the connections graphically to visualize the unions.

Question 2

Design an optimized Union-Find wherein path compression significantly reduces overall time. Discuss how many find operations can be consistently reduced in time.

💡 Hint: Consider how many steps the tree can collapse into after repeated finds.
