you are helping an army. if you don't send supplies, you would die. if the food drops to 0 all would die. if you run out of iron, the army could not fight. you will start with 100 food and 100 iron. it takes 10 seconds to produce 1 food and 100 seconds to produce 1 iron.The army eats 1 food every 60 sec.you decide how many food we produce.

def army(food, iron, seconds):
    while True:
        food -= 1
        seconds += 60
    if seconds % 10 == 0:
        food += 1
    if seconds % 100 == 0:
        iron += 1
    if food == 0 or iron == 0:
        print(food, iron)
        return
    army(food, iron, seconds)
    
army(100, 100, 0)
