You are given a non-empty sequence of non-negative integers terminated by a -1. The -1 is not part of the input sequence.

Question

You are given a non-empty sequence of non-negative integers terminated

by a -1. The -1 is not part of the input sequence. The sequence has

length at most 100, including the -1. There will be at least one

non-negative number.

You have to output the sequence of running averages, where:

The first average is the first input number.

The second output is the average of the first two input numbers.

The third output is the average of the first three input numbers,

and so on.

Output Format: You should output exactly 2 digits after the decimal

place. Different numbers in the output should be separated by

spaces. At the end, you should print a newline.

Answer 1

sum=0
n = 1
inp = input().split()
for i in inp:
i = int(i)
if(i== -1):
break
sum = sum+i
print("{:.2f}".format(sum/n))
n=n+1
