Help in ICPC 19 onine round problem

Revision en1, by bruj_kosh, 2020-10-15 06:56:15

Can someone give more insights on this ICPC-19 online round problem . I know it requires LIS and prefix sum but I can't develop the idea.

Before writing this blog I have searched for it's answer in ICPC India Online Round 2019 Discussion blog on Codeforces but no one has explained the idea there, thus I have no source to understand it ...

Thanx, regards.
