Souvik loves counting. He has a habit of generating any random logic and follow the same to start counting anything.
So one fine day he got an array of numbers. He, as usual could not resist the urge of counting and counted the number of elements of the array. But that was quite easy and Souvik didit quite easily. But he didn’t want the excitement to die down so easily. So he thought of a new logic.
He took the array and counted all the pair of integers such that i < j and A[i]>A[j], A being the array. As this is a tedious task, Souvik has turned to you to help him with the counting.
