Finding nth smallest and largest element in an array
Sort the array and return the nth smallest/largest element
Use quickselect algorithm for optimal solution
For nth smallest element, partition the array around pivot until pivot index is n-1
For nth largest element, partition the array around pivot until pivot index is len(array)-n
Handle edge cases like n being greater than array length
