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 sim_food(food_produce):
  food = 100
  iron = 100
  for time in range(0,600,10):
    food = food + food_produce
    food = food - (time/60)
    if food < 0:
      return 'you died'
  return 'you survived'
