Teacher: In this task, you are given a list of integers and an integer k. You need to find the kth largest element in the input list.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[128, 277, 83, 280, 193, 19, 111, 154, 41, 292, 29, 53, 232, 153, 131, 151, 121, 262, 270, 132], k=15
Solution: 111
Reason: 111 is the 15th largest element in the list.

Now, solve this instance: [203, 69, 186, 280, 93, 245, 223, 80, 170, 210, 106, 172, 121, 263, 159, 131, 162, 276, 213, 232], k=9
