## Problem Statement

#### Example:

``````Let ‘N’ = 4,  ‘Arr’ be [1, 2, 5, 4] and ‘K’ = 3.
then the elements of this array in ascending order is [1, 2, 4, 5].  Clearly, the 3rd smallest and largest element of this array is 4 and 2 respectively.

``````
##### Sample Output 1:
``````7 2
4 2
``````
##### Explanation of Sample Input 1:
``````Test case 1:
Here, ‘N’ = 4, ‘Arr’ = [5, 6, 7, 2] and ‘K’ = 3.
Elements of the array in ascending order are [2, 5, 6, 7]
Thus the 4rd smallest and 4rd largest elements of this array are 7 and 2 respectively.

Test case 2:
See problem statement for an explanation.
