Don't jump straight into your IDE. Professional problem solving follows a structured sequence:
— Donald Knuth
Finding subarrays or substrings (e.g., "Longest substring without repeating characters").
Get it working first, then make it fast, then make it clean.
Dealing with "Top K" elements or frequently updated minimums/maximums. 3. The "Rubber Duck" Debugging Technique
Finding the shortest path in an unweighted graph or tree level-order traversal.
Most DSA problems are variations of a few core patterns. If you recognize the pattern, the solution follows: When to Use It
