Union By Rank and Path Compression in Union-Find Algorithm

Don’t start Union By Rank and Path Compression in Union-Find Algorithm with jargon. Start with Union By Rank and Path Compression in Union-Find Algorithm on Rohit's board. That is the whole point.

Do Union By Rank and Path Compression in Union-Find Algorithm once by hand. one Union By Rank and Path Compression in Union-Find Algorithm step Rohit can write from memory. Change one input. Say the new result out loud.

Union By Rank and Path Compression in Union-Find Algorithm exists so Rohit can keep Union By Rank and Path Compression in Union-Find Algorithm on Rohit's board correct in a campus project.

Rohit ships Union By Rank and Path Compression in Union-Find Algorithm in a campus project. That is the use case worth saying.

Union By Rank and Path Compression in Union-Find Algorithm trap: skipping the failure case for Union By Rank and Path Compression in Union-Find Algorithm. Rohit loses marks for that every viva.

Place Union By Rank and Path Compression in Union-Find Algorithm next to nearby DSA work — one Union By Rank and Path Compression in Union-Find Algorithm step Rohit can write from memory is the link.

Close Union By Rank and Path Compression in Union-Find Algorithm with: “If I skip it, Union By Rank and Path Compression in Union-Find Algorithm on Rohit's board goes wrong like this: skipping the failure case for Union By Rank and Path Compression in Union-Find Algorithm.”

Exam tip

Board: Union By Rank and Path Compression in Union-Find Algorithm on Rohit's board. Dry-run Union By Rank and Path Compression in Union-Find Algorithm. Name the trap: skipping the failure case for Union By Rank and Path Compression in Union-Find Algorithm.

Example

# Union By Rank and Path Compression in Union-Find Algorithm
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

Union By Rank and Path Compression in Union-Find Algorithm: dry-run [4, 1, 3]. Say the list after one step.
