Question

3. The sequence of natural numbers a1, a2, ..., an is given. There are positive and negative elements in the chain. Calculate the product of negative elements P1 and the product of positive numbers P2. Compare the modules P2 and P1, indicate which of the modulus is greater.

Answer 1

s_1 = list(map(int,input("input sequence of natural numbers:\n").split()))
pos, neg = 1, 1
for num in s_1:
	if num > 0:
		pos *= num
	elif num < 0:
		neg *= num
if abs(pos) > abs(neg):
	print("product of positive numbers greater")
elif abs(pos) < abs(neg):
	print("product of negative elements greater")
else:
	print("product of negative elements eqval product of positive numbers")
