Give me a code to maximize pair decrements required to reduce all array elements except one to 0 and the other steps required given the following:
Maximize pair decrements required to reduce all array elements except one to 0 | Function to count maximum number of steps to make ( N - 1 ) array elements to 0.
Stores maximum count of steps to make ( N - 1 ) elements equal to 0.
Stores array elements.
Traverse the array.
Insert arr [ i ] into PQ.
Extract top 2 elements from the array while ( N - 1 ) array elements become 0.
Stores top element of PQ.
Pop the top element of PQ ..
Stores top element of PQ.
Pop the top element of PQ ..
Update X.
Update Y.
If X is not equal to 0.
Insert X into PQ.
if Y is not equal to 0.
Insert Y into PQ.
Update cntOp.

#Here is code to maximize pair decrements required to reduce all array elements except one to 0 and the other steps required.
 def cntMaxOperationToMakeN_1_0 ( arr , N ) :
	cntOp = 0
	PQ = [ ]
	for i in range ( N ) :
		PQ . append ( arr [ i ] )
	PQ = sorted ( PQ )
	while ( len ( PQ ) > 1 ) :
		X = PQ [ - 1 ]
		del PQ [ - 1 ]
		Y = PQ [ - 1 ]
		del PQ [ - 1 ]
		X -= 1
		Y -= 1
		if ( X != 0 ) :
			PQ . append ( X )
		if ( Y != 0 ) :
			PQ . append ( Y )
		cntOp += 1
		PQ = sorted ( PQ )
	return cntOp
if __name__ == ' _ _ main _ _ ' :
	arr = [ 1 , 2 , 3 , 4 , 5 ]
	N = len ( arr )
	print ( cntMaxOperationToMakeN_1_0 ( arr , N ) )
