Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
That is not as explanatory as you think it is, for example, if I would have this string 12341, I can think that obviating the three numbers in the middle, the answer is True, however as you previosly explain is just the number at the very middle. This kind of things most be explicit explain in the problem description.
I don't understand problem description, how this number is lucky: 17935 # 1 + 7 = 3 + 5, you are not adding 9 anywhere and do not mention nothing about this. Can anybody explain, please.
Test Cases should be hardest, I found wrong solutions that passed the test cases.
This is a long number(9223372036854775807) not BigInteger, you didn't understand my question, I didn't ask for change m from long to BigInteger, what I said is that seeing solutions, shouldn't pass if tested with that number, because of the way they are implemented. I just saying that test cases are weak, nothing else.
None solution should pass if tested with this as input parameter 9223372036854775807. Must use BigInteger instead.
