Answer 1

Code is running fine.
Do you getting any error? What is that?
{} after loop is unnecessary. No use. But it don't make any problem...

Answer 2

This looks like it is from a task.
Can you add the task description?

It will better to add error details.

I guess, you are having trouble in executing code here. While you run the code, in the pop-up window add all required inputs by code separated space or by line by line.
For your code : give inputs like
<length> <length number of inputs>
Ex:
2 <press enter>
12 <press enter>
13 <press submit>

Or
2 12 13 <submit>
