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:
[144, 18, 223, 63, 151, 196, 244, 85, 107, 170, 239, 126, 292, 159, 122, 97, 129, 229, 207, 202], k=1
Answer:
18
