Here is another classic puzzle called the Three Bucket Problem. In this scenario, there are an 8-liter bucket filled with water and empty 3-liter and 5-liter buckets. You solve the puzzle by using the three buckets to divide the 8 liters of water into two equal parts of 4 liters.
Expected Result:

//Fill the A and B with 4 litres of milk with out wasting any milk and C empty
