Hello Programmers, In this post, you will know how to solve the Compute the Average HackerRank Solution. This problem is a part of the HackerRank Linux Shell Series.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.
Problem
Given N integers, compute their average, rounded to three decimal places.
Input Format
The first line contains an integer, N.
Each of the following N lines contains a single integer.
Output Format
Display the average of the N integers, rounded off to three decimal places.
Input Constraints
- 1 <= N <= 500
- -10000 <= x <= 10000 (x refers to elements of the list of integers for which the average is to be computed)
Sample Input
4
1
2
9
8
Sample Output
5.000
Explanation
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).
Compute the Average HackerRank Solutions
#!/bin/bash #Easier way is to do using for loop read num ctr=$num sum=0 while [ $ctr -gt 0 ] do read x sum=$((sum + x)) ctr=$((ctr - 1)) done printf "%.3f\n" `echo "$sum/$num" | bc -l`
