+Hint 1: Use the `entry()` and `or_default()` methods of `HashMap` to insert the
+        default value of `TeamScores` if a team doesn't exist in the table yet.
 
 Hint 2: If there is already an entry for a given key, the value returned by
         `entry()` can be updated based on the existing value.
