You are given a permutation A of the first N positive integers. You are also given Q queries to perform one-by-one, the i-th is defined by a pair X; Y; and has the meaning that you swap the X-th number in the permutation with the Y;-th one. After performing each query you should output the number of inversions in the obtained permutation, modulo 2. The inversion is such a pair (i, j) that i < j and Aj > Aj. Input: 51 123 4 5 23 Output: 1
