How do I check my HackerRank output?

Using Debug Statements to Test Your Output Test different areas in your program by including debug print statements and print the output to STDOUT. For instance, include print statements such as printf() or Console. WriteLine() to test the output returned at different logical areas of your code.

3. Step 3: Assumptions and Pre-Conditions.
4. Step 4: Test Data.
5. Step 5: Steps to be Executed.
6. Step 6: Expected Result.
7. Step 7: Actual Result and Post-Conditions.
