AK 40 minutes early. Although because of carelessness I had one WA on each of the first three problems, causing 15 minutes of penalty time, the good news is that I probably will not need to do daily Cruel Coding check-ins this week. Perfect timing to go all in on preparing for Wednesday’s master’s thesis defense.

My three years of master’s study all depend on Wednesday. Finish it in one battle. Keep going, Forest!

Both this week’s weekly contest and biweekly contest went badly. Time to start the Cruel Coding check-in journey.

This week had the May Day holiday plus thesis plagiarism checking. My mood was made extremely anxious by the thesis. Just hold on for two more weeks; after getting through the defense, everything will be fine.

After the defense is over, I will be willing to do anything.

In the previous few weeks, because my China-site rating was too high, I did not dare to compete there, afraid of losing rating. I moved to the US site, and now I have also pushed the US-site rating to 2350. That rating is also too high. Later I plan to move back to the China site again, because the new recruitment season is approaching, and China-site sponsor gifts are relatively generous. Although last year I only ranked high enough a few times and received prizes, at least there was a reward and a small expectation.

Solution

A hand-speed contest. Recently my hand speed is far worse than before, and the last problem also took quite a bit of time because I was not familiar enough with it.

Actually, in a hand-speed contest, the algorithms for all problems are not hard. Thinking of the correct solution is quick, but implementing it quickly and bug-free tests every programmer’s fundamentals.

I have been exempt from check-ins for three consecutive weeks, and last night’s biweekly contest also went pretty well as a hand-speed contest.

The recent weekly contests have indeed become somewhat easier. It seems I am still more suited to easy problems. Hard+ problems are still not quite my thing.

The contest time was 7 a.m. to 10 a.m. Beijing time on the 19th, and it happened that I had to submit the first draft of my graduation thesis at 2 p.m. Recently I had been busy writing the thesis, so I did not participate in Round B. Now I have already passed the age of campus recruitment, so competing in Kick Start is purely for fun.

Post-contest upsolving.

It had been a long time since I solved all four problems and entered the top 500. Finally I can skip check-in.

I had been checking in for seven consecutive weeks and was almost unable to take it anymore. Recently LeetCode’s difficulty has risen quite a bit, and many strong players have joined too. Achieving both four solved problems and top 500 is indeed not easy.
