Hi Marisa: Thanks for contributing some problems to Cody! I want to encourage you to make your problems more general so that there's more than just one input and out output. Maybe you could make this problem into something more like this: "Round the given number to the nearest integer." Then pass in several numbers, not just one.

Generate N equally spaced intervals between -L and L
