## Problem: Introduction to Sets Hacker Rank solution

Now, let’s use our knowledge of sets and help Mickey.

Ms. Gabriel Williams is a botany professor at District College. One day, she asked her student Mickey to compute the average of all the plants with distinct heights in her greenhouse.

Formula used:

Function Description

Complete the average function in the editor below.

average has the following parameters:

• int arr: an array of integers

Returns

• float: the resulting float value rounded to 3 places after the decimal

Input Format

The first line contains the integer, , the size of .
The second line contains the  space-separated integers, .

Constraints

Sample Input

``````STDIN                                       Function
-----                                       --------
10                                          arr[] size N = 10
161 182 161 154 176 170 167 171 170 174     arr = [161, 181, ..., 174]
``````

Sample Output

``169.375``

Explanation

Here, set ([154, 161, 167, 170, 171, 174, 176, 182]) is the set containing the distinct heights. Using the sum() and len() functions, we can compute the average.
