Write me a code to find the last positive element remaining after repeated subtractions of smallest positive element from all Array elements and the other steps required given the following:
Find the last positive element remaining after repeated subtractions of smallest positive element from all Array elements | Function to calculate last positive element of the array.
Return the first element if N = 1.
Stores the greatest and the second greatest element.
Traverse the array A [ ].
If current element is greater than the greatest element.
If current element is greater than second greatest element.
Return the final answer.

#Here is code to find the last positive element remaining after repeated subtractions of smallest positive element from all Array elements and the other steps required.

	greatest = - 1 ; secondGreatest = - 1 ;
	for x in arr :
		if ( x >= greatest ) :
			secondGreatest = greatest ;
			greatest = x ;
		elif ( x >= secondGreatest ) :
			secondGreatest = x ;
	return greatest - secondGreatest ;
