IZHO 2014 — Problem E
Автор radoslav11, история, 10 лет назад, По-английски

Hello codeforces,

I was solving IZHO problems from past years but I couldn't solveIZHO 201problem E — "K blocks" (link; the second problem). I wrote the O( N * N * K ) dp solution, but I'm not sure how to reduce it to O( N * K ). I tought of Convex hull trick, but unfortunately i don't know how to apply it.

So can someone share his solution? Thanks ;)
