Problem 7 (200pts)

A pure strategy only has a fixed number of possible argument values. In a game to 100, there are 100 possible score values (0-99) and 100 possible opponent_score values (0-99), giving 10,000 possible argument combinations.

Implement is_always_roll, which takes a pure strategy and returns whether that strategy always rolls the same number of dice for every possible argument combination.
