I don't know why this code runs
After reading answers from other questions, I understand that I have to change DBObject to User to pass the verification. However, even without changing it, the code displays correct answer. Could someone please explain why it displays correct answer?

1,000 Exceptions, but Code Displays Fine
I felt like I had all of the steps worked out and the code made sense to me. But when I ran and verified... it blew up in my face. A lot of exceptions and red font on the console, not a single green check, and not even a coherent-looking grid. Any hints to help me advance on this one?

What's wrong if the output's right?
The code I've written reads 6 strings from the console, finds duplicated ones among them, substitutes them with null and produces the expected output. Why does it still fail validation (in particular, does not meet the 2nd requirement)?

The task is to write code to convert a decimal to a binary number and vice versa. I've kind of finally written the 'toBinary' method that works but the 'toDecimal' one keeps making an error. I still can't see what I'm doing wrong.
