Hello, following my previous blog, I'm adding the new problems I found interesting/teaching, so let's get into the problems

Note: these problems are mostly for the range of [pupil, expert] level, an average specialist with a bit of sweat will be able to solve them all

The problems aren't in any specific order but higher problems may be a bit easier
These problems' requirements are intermediate dp, binary search, pure logic, algorithmic thinking, and math.
and I've solved all of them so feel free to check my submissions if u wanted
