Problem Description bobo has a sequence a1,a2,-,an. He is allowed to swap two adjacent numbers for no more than k times. Find the minimum number of inversions after his swaps. Note: The number of inversions is the number of pair (i,j) where 1≤i<j≤n a…
Give an array A, the index starts from 1. Now we want to know B i =max i∤j A j Bi=maxi∤jAj , i≥2 i≥2 . InputThe first line of the input gives the number of test cases T; T test cases follow. Each case begins with one line with one integer n : the si…
