B"Chaneka, Pak Chanek's child, is an ambitious kid, so Pak Chanek gives her the following problem to test her ambition. Given an array of integers [A_1, A_2, A_3, ldots, A_N] . In one operation, Chaneka can choose one element, then increase or decrease the element's value by 1 . Chaneka can do that operation multiple times, even for different elements. What is the minimum number of operations that must be done to make it such that A_1 x A_2 x A_3 x ldots x A_N = 0 ? The first line contains a single integer N ( 1 <= q N <= q 10^5 ). The second line contains N integers A_1, A_2, A_3, ldots, A_N ( -10^5 <= q A_i <= q 10^5 ). An integer representing the minimum number of operations that must be done to make it such that A_1 x A_2 x A_3 x ldots x A_N = 0 . In the first example, initially, A_1 x A_2 x A_3=2 x (-6) x 5=-60 . Chaneka can do the following sequence of operations: In the third example, Chaneka does not have to do any operations, because from the start, it already holds that A_1 x A_2 x A_3 x A_4 x A_5=0 x (-1) x 0 x 1 x 0=0 "...
