I had the same time out problem. Did you find a solution?

Did you eliminated the server timeout error. I have been coding in javascript and I have the same error.

I know that you posted this some time ago. I had the same problem with memory overflow. I refactored my code and now I dont have that problem. But now I have an exit code, because of execution timeout. Did you finally solved it?

++++++let name = names.shift()
++++++names.push(name, name)
++++++num += 1

++++++return names[r-num-1]
