Most DSA problems are variations of a few core patterns. If you recognize the pattern, the solution follows: When to Use It

Get it working first, then make it fast, then make it clean.

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. The Strategy: The "Three-Pass" Approach
