It's the 19th day, and I participated in a CodeChef contest today. Managed to solve the first two questions successfully, but unfortunately, I encountered a Time Limit Exceeded (TLE) issue with the third one. I spent the entire duration brainstorming and optimizing the code, and I realize that dwelling on optimization might be my main setback. Moving forward, I'll aim to swiftly transition to the next question, attempting to solve it efficiently without lingering too much on a single problem. Lessons learned, and I'm determined to apply them in future contests.
