DSA - 1 new (Matrix Simulation)

LC 54. Spiral Matrix

Insight: Sometimes the most straightforward approach is the correct one. The problem is best solved by actually simulating the spiral traversal using 4 pointers (top, bottom, left, right) and iterating layer by layer.

Key Learning: There was an initial hesitation to fully trust the simulation approach — it felt too “simple” or brute-force. However, this solution is already asymptotically optimal (O(n × m)), which means there is no need to over-optimize further.

When a solution is asymptotically optimal, avoid unnecessary micro-optimizations that reduce clarity.

Reflection

Couldn’t revise or practice further today. Got occupied with family commitments, and later in the day, energy levels were low — likely due to health. Decided to rest instead of forcing productivity.

Takeaway: Consistency is important, but so is listening to the body. Recovery is also part of the process.
