NOI (Singapore) is an annual, and well, prestigious, programming and algorithmic problem-solving contest for secondary school to junior colleges and polytechnic students in Singapore.
I was first exposed to competitive programming last year when I was in Secondary 3 by my Secondary 4 scholar senior. I told myself, “Sure, why not? Sounds quite interesting.”, and it was! My senior also invited me to participate in NOI 2025, which I did. I didn’t get into the finals, which was very okay to me back then.
I’m still continuously learning algorithmic problem-solving/competitive programming. This year, I decided to participate again and got into the finals! I even got the bronze medal, which was a nice surprise!
Here are some things I’ve learnt.
