Answering Coding Questions

Overview 

Coding questions are the most popular type of questions in HackerRank Tests. The hiring company's test setter designs your Tests to include relevant coding questions based on the skills and programming knowledge required for a particular job role.

The HackerRank Test platform supports assessments in multiple programming languages with an intuitive and in-built code editor to help you solve coding challenges.

Coding questions may require you to complete the logic of a given function, and the remaining portions of a program may be non-editable. Alternatively, some questions may require you to write a complete program as the answer.

Answering Coding Questions 

Here is a quick video to get you started with the Answering Coding questions workflow.

Or, if you prefer to follow directions, here are the steps for your ready reference.

Steps 

• Read and understand the problem statement and the various constraints described in the problem. This helps to avoid any rework and saves time in Tests.
• Take a quick tour to familiarize yourself with the code editor and learn how to run and submit code. Click on the question mark icon and select Show Tour.
• The Languages option lists the programming languages permitted by the test setter to answer the question. Select the required language from the list.
• Once you have answered your question, click on Run Tests to test your code.  
• You can also click Run code to compile. You can also use the keyboard shortcut (cmd+return) to run your code, but please note if you use a keyboard shortcut to run your code, your cursor will automatically move to the following line in the code editor.
• Once you run your code, Test cases execute to validate your answer. If permitted for your Test, you can use the IntelliSense-like-code-autocomplete capability in the editor to avoid compilation and syntax errors and make effective use of your Test time.
• Debug your code using debug print statements or using the "Custom Inputs" option

• Refer to the following topics for detailed information about debugging code in your Test:
• Debugging the Logic in Functions
• Debugging a complete program

• Click Submit to submit your answer. You can revisit the question, modify the code, re-compile, and resubmit the answer any number of times before the test times out.
