Object.keys doesn't work on an iterable object ( well, it does, but it doesn't do what you want it to do ). You have to iterate it. Follow the link in the description and read up on the protocol.
The first value there is your answer, and you can see there are more than one 0 not at the end. Probably you're mutating the array at the same time you run through it, skipping values.
About what +0 is, you can see that's 0, don't mind the + before it, it's probably chai adding it in the assertion.
That depends on what went wrong...
Got the same error
Your solution crashes for large numbers. Try running it with
n=160000.If you have execution timeout, then the solution does not pass, despite of returning correct answers.
See if this paragraph helps.

no, it returns with commas
There is a trick to do it, which doesnt require searching for every possible combination. Hint: think about why its specifically powers of 2?
