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 ∑ ...
