I have been doing cp for almost 2 years. I am supposed to get a job for obvious reasons. But applying for jobs does not seem like very productive use of time. Even a lot of jobs does not look like productive use of time to me. But regardless I need to get a job anyway.

I am not asking for a job if anyone's wondering.

I just want to know how to control this endless grinding loop and focus on other things in life?

Hi, this is Leetcode POTD. I am not looking for dp solution as there are plenty of those on leetcode. I was wondering if there's combinatorics solutions for this problem? More formally can this problem be solved for bigger constraints such as 1 <= m, n <= 1e5. If so, how can anyone provide an explanation?

Thank you for trying this problem.

Actually why don't they post all the solutions, from the most optimized solution to the least optimized solution just above brute force?

Or it they are posted can somebody tell me how to find them?

This is my actual account. So yeah this problem is way beyond my level. I tried reading the editorial, but couldn't understand anything. So I would love if somebody could explain it in a way that even I can understand. Problem Link.

The reason I'm trying this problem is to understand at what level red players are playing at.

Regardless, Thankyou for taking time to read this post.
