The second pop is redundant. We only need the min value in numbers, we don't need to pop it.

Well, it makes a change in the original list so it doesn't answer the problem.

thanks for your reply. if the problem was big then I would make a copy. for a simple problem like this i think it is ok. But copying list is always a good practice.

Using index method is a great idea! Thanks for inspiring me. Maybe you could make a Copy of the array,leaving the array unchanged.
