Coding Interview Patterns

Concept map is drafted. Clips are being curated.

The learning path below is fixed by L3; trusted-creator clips are being selected for each node. Know a great video for this? Suggest it.

1. 01Two pointers & sliding window. The linear-scan patterns that solve half of all array questions.
2. 02BFS, DFS and when to use each. Traversal as a template — shortest paths, islands, dependencies.
3. 03Dynamic programming, demystified. Recognising overlapping subproblems before you write any code.
