Test Case 11: The capacity of the bucket is 55 liters but it is already filled with 44 liters of water. Adding 11 more liter of water to the bucket fills it to (4+1)=5(4+1)=5 liters. If we try to fill more water, it will overflow.

Test Case 22: The capacity of the bucket is 1515 liters but it is already filled with 66 liters of water. Adding 99 more liters of water to the bucket fills it to (6+9)=15(6+9)=15 liters. If we try to fill more water, it will overflow.
