In this task, you are given a list of integers and an integer k. You need to find the kth smallest element in the input list and return that.

Let me give you an example: [163, 290, 90, 51, 96, 86, 282, 265, 10, 85, 91, 201, 68, 126, 26, 228, 229, 236, 31, 71], k=14
The answer to this example can be: 201
Here is why: 201 is the 14th smallest element in the input list.

OK. solve this:
[13, 25, 221, 106, 90, 132, 47, 31, 292, 123, 285, 186, 151, 125, 191, 261, 230, 159, 252, 259], k=4
Answer:
47
