I started 3 minutes late but still got 2nd! Anyways, explanations start at 10:11. If they are a bit unclear, feel free to ask questions in the comments below so that I can improve!
Bonus: Solve the 2nd problem in O(nlogn), with the modification that you need to count the number of subarrays of any length! (atcoder.jp/contests/arc075/tasks/arc075_c)

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
