These patterns appear often because they match common UI behavior:

Two pointers (e.g., validating substrings, merging sorted inputs)
Sliding window (debounced search, scrolling logic, timed intervals)
Hash maps and sets (tracking seen values, grouping UI elements, caching)
Stacks (undo/redo logic, evaluating expressions)
Queues (breadth-first traversal of structures like menus)

You must demonstrate strong intuition for these.

2. Tree and Graph Problems with UI Mentality

Airbnb doesn’t expect deep graph theory, but you should be comfortable with:

BFS/DFS for hierarchical data (menus, categories, component trees)
Handling adjacency lists
Finding paths or flattening nested structures

These align with many real-world UI needs.

3. String and Array Manipulation

Airbnb frontend coding challenges frequently include:

Parsing strings
Cleaning data
Splitting or joining structured text
Frequency counting
Deduplication
