Resumed coding after 10 months, and gave a contest yesterday

I really enjoy coding, but as a hobby, NOT as a passion. Now that I have had time to think about it, I actually enjoy the mathematical aspect and thus the only coding I enjoy is DSA/CP. Gave a contest after some 12 months. Subpar performance in terms of speed, but glad to see that I never forgot my coding ability and logical thinking. Scored 12 points (3/4) in approx 1 hour. Solved the hard question as well, though it took me quite a lot of time (solved after the contest ended). Had a really innovative approach in terms of manipulating the mono stack with a different function that simply greater/lesser. I still need to prove why it works with a purely mathematical approach and not simply based on intuition. I wish there was a SDE position where we were supposed to code DSA/CP instead of WebD/AI-ML😭😂 If anyone wants to discuss my code please comment https://preview.redd.it/8s3nla379qqg1.png?width=1395&format=png&auto=webp&s=0f6bc7da035c1dc84e616cff452e2b74b4a7526b
