Problem Overview

• Count unordered pairs (i, j) where 0 <= i < j < n such that arr[i] XOR arr[j] > arr[i] AND arr[j].
• Input: array of n positive integers; Output: long integer count of such pairs.
• Domain: bitwise operations and array processing, typical in coding interview settings.
• This interview question/problem is from Ibm interviews.
• Constraints: not specified.
