15 Questions
What is the key characteristic of the sets formed in the Union Find pattern?
The sets are non-overlapping and contain unique elements
What is the purpose of the find(x) operation in the Union Find pattern?
To determine the representative element of the set containing x
What is the primary data structure used to implement the Union Find pattern?
Array
What is the purpose of the union(x, y) operation in the Union Find pattern?
To merge the sets that contain x and y into one set
How do the sets formed in the Union Find pattern maintain their structure?
Each set forms a tree data structure with a representative element at the root
What is the primary use case of the Union Find pattern?
To maintain a collection of disjoint (non-overlapping) sets of elements
What optimization helps ensure that elements in a merged tree have the shortest path to the root in the union find pattern?
Union by rank
What does path compression in the union find pattern aim to reduce?
The length of the path to the root
Which function is used to represent the amortized time complexity after applying the union find optimizations together?
$O(\alpha(n))$
What problem type can be best solved using the union find pattern?
Image segmentation
Why is union find preferred over breadth-first or depth-first search in certain scenarios?
It reduces time complexity for certain operations
In what type of digital image processing does union find particularly excel?

What real-world application involves connecting devices and determining if a path exists between them?
Network connectivity
'Hex' game uses connections between pieces of the same color. What does this technique help achieve in the game?
Identify winning configurations
What does union by size aim to determine when merging trees in the union find pattern?
Closeness of elements
