#in this file we will write 2 functions
#1. sumCount thta has one parameter, size - the number of input integers 
#Function returns the amount and sum of even numbers among inputs

#2. average - has two parameteres, size and sum - amount of evens and sum 
#of evens. Function returns average of evens

	for i in range(size):
		n = int(input(" "))
		if(n%2 == 0):
			countEven+=1
			sumEven+=n

	return countEven, sumEven
