Count of indices pairs such that product of elements at these indices is equal to absolute difference of indices | Function to count the number of pairs ( i , j ) such that arr [ i ] * arr [ j ] is equal to abs ( i - j ).
Stores the resultant number of pairs.
Generate all possible pairs from the array arr [ ].
If the given condition satisfy then increment the value of count.
Return the resultant count.
