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.

food = 100
iron = 100
timestep = 0
max_time = 100000
while food > 0 and iron > 0 and timestep < max_time:
  time.sleep(10)
  food = food + 1
  time.sleep(100)
  iron = iron + 1
  time.sleep(60)
  food = food - 1
  timestep = timestep + 1
  print(food, iron, timestep)
