Another problem coincidence
By Webbly, history, 20 months ago, In English

Recently, I was solving AtCoder problems and came across this task https://atcoder.jp/contests/abc125/tasks/abc125_d, that is very similar compared to recent Div.4 E https://codeforces.net/contest/1791/problem/E

This problem from a small contest from codechef is almost identical to that problem too (that contest was held in 2022), the only difference is the problem 1791E - Negatives and Positives is on an 1D array and the codechef problem is on a 2D array.

I think the idea of that kind of problem is easy to think of.
