Got 10th this time, not ideal but still decent. Explanations start at 21:35. If they are a bit unclear, feel free to ask questions in the comments below so that I can improve!
Bonus for A: The same problem, but the matrix is hidden from you. You can ask for any element of the matrix at most k times. Can you find the number of negative elements with at most 700 queries? How about 199?

Im attempting to solve the first 150 problems of the CSES Problem Set (in 12 hours?) live.
The problem set is here: https://cses.fi/problemset/
I will try to use no prewritten templates, but maybe some Wikipedia?
Also, this happens to be my 100k sub special.
Solved everything in a bit under 11 hours, played Typeracer and answered a few questions for the last hour :P
The timer was accidentally reset 2 times during the stream
