Hi, here's your problem today. This problem was recently asked by LinkedIn:

Given a list of numbers and an integer k, partition/sort the list such that the all numbers less than k occur before k, and all numbers greater than k occur after the number k.

```
def partition_list(nums, k):
# Fill this in.
print(partition_list([2, 2, 2, 5, 2, 2, 2, 2, 5], 3))
# [2, 2, 2, 2, 2, 2, 2, 2, 5]
```
