Realizing that the forces are equal, each of them had followed the only course possible - to call for help. Umbert sent for the reinforcement his coachman on a horse, and Sir Ronald used a family horn that sounded more than once in hot battles. The knight's castle was close enough for the call to arms was heard back there. Nobody quite knew where the Umbert's accomplices were located, and this made it difficult to come up with a strategy for the battle ahead.
Fortunately, the reinforcements for both sides arrived almost simultaneously. Now it was more than a question of the girl's honor. There was no peaceful solutions to this matter. One of the two armies must be destroyed.
In the previous mission - Warriors - you've learned how to make a duels between 2 warriors happen. Great job! But let's move to something that feels a little more epic - the armies! In this mission your task is to add new classes and functions to the existing ones. The new class should be the Army and have the method add_units() - for adding the chosen amount of units to the army. Also you need to create a Battle() class with a fight() function, which will determine the strongest army.
The battles occur according to the following principles:
at first, there is a duel between the first warrior of the first army and the first warrior of the second army. As soon as one of them dies - the next warrior from the army that lost the fighter enters the duel, and the surviving warrior continues to fight with his current health. This continues until all the soldiers of one of the armies die. In this case, the battle() function should return True, if the first army won, or False, if the second one was stronger.
