Small hint if you are having trouble with batch #2: Your data type has to be able to store AT LEAST 64-bits, so you have to use a long variable type.

Thanks! I was having trouble with batch 2! Try 1000000000 and 1000000000 if you don't see why.

Is Batch #2 even solvable?

Java's String.format some how doesn't work... Figured out how to solve it without using String.format
