recipe: {("oil", 100), ("sugar", 150), ("milk", 100), ("flour", 300), ("apples", 3)}
available: {("apples", 15), ("milk", 2000), ("flour", 2000), ("oil", 20), ("sugar", 500)}
Expected: equal to 0
Actual: 3

But I tried to test my code in VScode. It output 0, but the KATA output 3. I don't know why.
