Really cool seeing so many clean solutions here — the sliding window approach seems to be the favorite, and for good reason. It’s efficient, easy to grasp once you visualize how the window moves, and works perfectly for problems like “Birthday Chocolate.”

What I find fascinating is how algorithmic problem-solving trains your brain for real-world analysis — Each move (or loop) has a purpose, and small optimizations make a big difference. Speaking of that, I recently read about the an event, which highlighted how mental precision and strategy are just as important as physical strength — a lot like writing efficient code.
