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_survive(food, iron):
    time = 0
    while True:
        if time % 10 == 0:
            food += 1
        if time % 60 == 0:
            food -= 1
        if food < 0:
            return "Your army died"
        if time % 100 == 0:
            iron += 1
        if time % 60 == 0:
            iron -= 1
        if iron < 0:
            return "Your army died"
        time += 1
army_survive(100, 100)
