CodeChefOpen on judge ↗

Given an array A with n elements. There are q queries of the form (l, r). For each query you need to find the number of pairs (i, j) such that l ≤ i ≤ j ≤ r and and which satisfies the following condition: Ai ≤ Ai ^ Ai + 1 ≤ ... ≤ Ai ^ Ai + 1 ^ ... ^ Aj, where ^ is XOR. Input - The first line contains one integer n, denoting the number of elements. - The second line contains n space-separated i
