Given integers, compute their average, rounded to three decimal places.
The first line contains an integer, .
Each of the following lines contains a single integer.
Display the average of the integers, rounded off to three decimal places.
( refers to elements of the list of integers for which the average is to be computed)
The '4' in the first line indicates that there are four integers whose average is to be computed.
The average = (1 + 2 + 9 + 8)/4 = 20/4 = 5.000 (correct to three decimal places).
Please include the zeroes even if they are redundant (e.g. 0.000 instead of 0).
