Недавно, я решал AtCoder и встретил задачу https://atcoder.jp/contests/abc125/tasks/abc125_d, которая ничем не отличается от задачи Е недавнего Div.4 https://mirror.codeforces.com/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.
