How to solve easy problems?
By TheScrasse, history, 5 hours ago, In English

Today I've taken part in AtCoder Regular Contest 186, solved problem E and spent the remaining 90 minutes not solving anything.

Then I've taken part in Codeforces Global Round 27 and spent 90 minutes solving 2035D - Yet Another Real Number Problem.

How to stop being stupid?

I'd gladly exchange my skill of solving easy problems with your stupidity

I would like to understand your thought process ?

were you stuck in finding the core-logic ?

Or were you stuck with implementation ?

In my case, I had found logic in the first 30 minutes while solving D. But I had to think a lot while implementation, to avoid getting into large numbers. Because, there would have been integer overflows. I had to split each number into two parts. 1) odd number, 2) power of 2's in that number. This took me more than 40 minutes to do it fully. .

    I was stuck mainly because I found out the stack is small (length $$$\leq 8$$$?) and I was trying to iterate on subsets to remove instead of just removing the last element.

I've taken part in Codeforces Global Round 27 and spent too much time solving 2035C, so I solved 2035D instead.

I think it's not uncommon to find that a problem's point value or number of solves doesn't always correspond to how difficult the problem is for you? At least you solved D in the end. :)

For example, I thought that problem A from today's ARC was harder than all the others, and that F from today's global round was comparable or easier than D.
