Cities With at Least Three Students

Count the students in each city inside a CTE named per_city (columns city and students), then select city and students from it for the cities with three or more students. Sort by students descending, then city.

Expected result:

+-------------+----------+
| city        | students |
+-------------+----------+
| Toronto     |        8 |
| Ottawa      |        5 |
| Hamilton    |        4 |
| Mississauga |        4 |
| Kingston    |        3 |
| London      |        3 |
