#Here is code to count pairs from an array having equal sum and quotient and the other steps required.

	mp = { }
	for i in range ( n ) :
		y = a [ i ]
		if ( y != 0 and y != 1 ) :
			x = ( ( ( y * 1.0 ) // ( 1 - y ) ) * y )
			count += mp . get ( x , 0 )
		mp [ y ] = mp . get ( y , 0 ) + 1
	return count
arr = [ - 4 , - 3 , 0 , 2 , 1 ]
N = len ( arr )
print ( countPairs ( arr , N ) )
