Finding the shortest path in an unweighted graph or tree level-order traversal.

Finding subarrays or substrings (e.g., "Longest substring without repeating characters"). Problem Solving in Data Structures & Algorithms...

Always identify the "Brute Force" solution first. Even if it’s inefficient, it guarantees a baseline for correctness and helps you see where the bottlenecks are. Finding the shortest path in an unweighted graph

Effective problem solving in isn’t just about knowing code; it’s about having a repeatable mental framework to dismantle complexity. Whether you're prepping for interviews or optimizing production code, here is the blueprint for mastering the logic. 1.
