Cf868f yet another minimization problem
Webmemory limit per test. You are given two arrays a and b, both of length n. You can perform the following operation any number of times (possibly zero): select an index i ( 1 ≤ i ≤ n) and swap a i and b i. Let's define the cost of the array a as ∑ i = 1 n ∑ j = i + 1 n ( a i + a j) 2. Similarly, the cost of the array b is ∑ i = 1 n ∑ ... WebCF868F YET Another Minimization Problem (Decision Monolecule) Topic Description: Given a sequence, divide it into k subsequent sequences. The cost of each subsequence is the logarithm of the same element.

WebYet Another Minimization Problem. DP Let fi,j denote the minimum cost of dividing the first i into j intervals. So fi,k=min{fj,k+cost(j+1,i)} It's like the old CF833B routine that can be maintained with segment trees. But because cost()=ai(ai_1)2, which is not maintained with segment trees, it can not do so.
