Objective
In this challenge, we practice calculating quartiles. Check out the Tutorial tab for learning materials and an instructional video!
Task
Given an array, , of integers, calculate the respective first quartile (), second quartile (), and third quartile (). It is guaranteed that , , and are integers.
Input Format
The first line contains an integer, , denoting the number of elements in the array.
The second line contains space-separated integers describing the array's elements.
Constraints
, where is the element of the array.
Output Format
Print lines of output in the following order:
The first line should be the value of .
The second line should be the value of .
The third line should be the value of .
Sample Input
9
3 7 8 5 12 14 21 13 18
Sample Output
6
12
16
Explanation
. When we sort the elements in non-decreasing order, we get . It's easy to see that .
As there are an odd number of data points, we do not include the median (the central value in the ordered list) in either half:
