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 Xr-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 i) thatisi and A: > A:

Example: Using python
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; Yj 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.
