#Write a program that reads a sequence of non-zero integers. First zero 
#value will terminate the input. The program finds and prints the number 
#or inputs, their sum and average. 
#Solution with Functions:
def process():
	count=0
	sum=0
	#we have to read first input BEFORE the loop so we can use the condition 
	#of non-zero inputs
	num=int(input("enter non-zero integer "))
	while(num!=0):
		count=count+1
		sum=sum+num
		num=int(input("enter non-zero integer "))
	if(count>0):
		average=sum/count
		return count, sum, average
	else:
		return count, -1, -1
def main():
	count, sum, average=process()
	if(count==0):
		print("no inputs")
	else:
		print(count, sum, average)
main()
