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: [102, 292, 198, 213, 21, 181, 274, 188, 127, 241, 66, 242, 291, 164, 95, 268, 212, 290, 262, 17], k=20
