Swapping Integers

Sneklang makes it easy to swap two values:

cool_person = "Lane"
uncool_person = "TJ"
cool_person, uncool_person = uncool_person, cool_person
print(cool_person)  # TJ
print(uncool_person)  # Lane
# (get rekt lane)

Assignment

Before we do something more tricky, let's start with just swapping some integers. Complete the swap_ints function. It accepts two pointers to integers, and should swap the values of the integers they point to.

You'll need to use a temporary variable to store one of the values while you swap them.
