Assessment 4_12_sample

Instructions

This assessment is designed to be completed in 10 minutes or less.

Copy the template below and get all the test cases to pass. Hard-coding answers will not receieve credit; your solution must work for valid arrays.

The problem

Imagine that the user provides a one dimensional list. Return a sorted version of this one dimensional list. For example, if the user enters [3, 4, 1, 2, -1] your code would return [-1, 1, 2, 3, 4].

Please do not use any Java code or libraries that we have not covered in class; this defeats the purpose of the assessment and will not receive credit.
