Welcome to Sample Test

1. This is a sample test to help you get familiar with the HackerRank test environment.
2. If the code area contains the function signature, just complete the function alone, we'll take care of the main function, headers, etc
3. Do not close the browser window/tab before you submit your final answers. If you do so, we cannot guarantee that your work will be saved.
4. Solve code challenges on HackerRank if you'd like to practice more before taking the real test.
