For her current programming project, Soriya needs to first construct the array which has length . However, to entertain herself, she decides to add the elements in the order described by the permutation . That is, for her th insertion, she will add the element to its position in the array. Since Soriya has nothing better to do with her life, she wonders: how many inversions will the array have after each insertion? An inversion is a pair of indices such that and .
Input Specification

The second line consists of positive integers, the array .
The third line consists of positive integers, the permutation .
Output Specification
Output lines, the th of which containing a single integer, the number of inversions after Soriya adds her th element.
