Hackerneck 1
Complete the Coding Challenges
Alright,
let’s get started with the Coding Challenges! You’ll have 4 hours to
read through the instructions, complete the challenges, and submit them
to us.
INSTRUCTIONS FOR THE CHALLENGEs
- You’ll solve the 4 Coding Challenges in HackerRank using JavaScript.
- You may use any online documentation or reference (e.g., MDN, Stack Overflow) as long as you are not looking directly for the solution to the challenge. You may also use this JS Cheatsheet to help you with syntax.
- The first challenge, “Solve Me First”, serves to explain how HackerRank works. Take a moment to watch this 7-minute video explaining how HackerRank works.
- Each challenge has pre-populated code to help you get started. You don't need to touch or understand it to solve the challenges, but if you're curious, here's an explanation of STDIN and STDOUT.
- You may have to switch the language to JavaScript in HackerRank manually. Watch this short video to learn how to do it.
Note: HackerRank lists this option as "JavaScript (Node.js)", but you don't need to know Node.js to solve them; basic, vanilla JavaScript will be all that you will need. - Use the “Run Code” button to see if your code passes the basic or custom tests. Use the “Submit Code” button to see if your code passes all test cases, including edge cases.
- Once you're done with the four challenges (or the 4 hours are up), come back to this page to submit your results.
Note: If you fail some of the tests, you can always go back to modify your solution by clicking on “Open in editor” and submitting it again. We don’t care how many times you submit your code in HackerRank, so feel free to keep trying until you get it right. Even if you weren’t able to pass all the test cases, you should still submit them so that we can recommend ways to improve before you try again.
