How to create a HackerRank Contest?

• Hello everyone this is R.Prabhakara Arjun,🕺
• I faced a hard time creating a HackerRank contest without proper guidance and clear documentation.
• If you’re a fellow tech enthusiast facing the same challenge, you’re not alone! To help others avoid the confusion I went through, I’ve documented my full experience and provided a step-by-step guide to setting up a contest.
• The complete markdown is there in my git: HACKER-RANK-CONTESTS

I hope this helps all the aspiring contest creators out there. Happy coding!

HACKERRANK-CONTESTS🚀

ABOUT 📘

• The below documentation will guide you how to create a coding contest
• what's given the below is a part of DSL(Domain Specific Language) which is like a pesudo code that will create code blocks of your defenition.
  • DSL helps you create code stubs like main function and solution function
  • You can decide the input types and parameters.

STEPS TO CREATE A CONTEST 🛠️

• STEP-1: Siginin and login into hackerrank got to Dashboard
• STEP-2: Click the top right corner which contains the logo,you will get to see the profile->dark mode->leaderboard->settings->bookmarks->network_>submission_>administration->logout
  • Choose the administration
• STEP-3: Click create contest button and exploration is up to you.

TIPS 💡

• Moderators are the one who is like admin in whatsapp group,they have acess to your contest and they can manage them
  • If you are going to make an official contest with large number of people do it as a team,do it with moderators.
• Challenges are the place where you create your own question or (in-built)make use of already made question form hacerrank.

STEPS TO CREATE A CHALLENGE 🧪

• You will come across the word challenges these are custom made problems.
  • You can build your own question
• Go to administration page click here
• Choose Manage chalanges
• STEP-1: Click Create challenge
• STEP-2: You can always change this create page later. so make it as a simple dummy page(fill rubbish),just give a proper Challenge Name as of now and minimal description u can change it later.
• STEP-3: In details you can change the entire description,you can modify problem statement,etc.
  • Note everything is a MarkDown so you can style it,it is saved as .md
  • You can preview the content
• STEP-4: here comes the fun part
  • Go to Code stubs,this is the place where you will create stub which will generate template code in all languages you have selelcted in Langugaes
  • Paste the below code and click Generate Code stubs then you are ready to go.

EXAMPLE1 ✏️

function(boolean,isPower,integer n)
integer(n)
invoke(boolean,result,isPower,n)
print(boolean,result)

EXAMPLE2 ✏️

function(2d_integer_array, findMe2, integer l, integer m, integer n, integer target, integer_array arr)
integer(l) integer(m) integer(n) integer(target)
Array(integer, arr, l, single)
invoke(2d_integer_array, result, findMe2, l, m, n, target, arr)
print(2d_integer_array, result)

How it works? ⚙️

• function creates a function with syntax given below
• inputs are given in the next few lines with synatx given below
• invoke calls it
• print makes the user get to see the output.

TEST CASES 🧪

• NOTE: The input is given in the format how you gdefined the code in your stubs(DSL)
• output is just the answer for the input what you gave.
• You can give it as sample and explain it. This is visible once you click the pencil option
• Also You can change strength for each test case.
• To create a large number of test cases you can write a custom script that will define files as

testcases.zip
├── input00.txt
├── output00.txt
├── input01.txt
├── output01.txt
└── ...

• You can code solution for you code and create a script(py code,java code) to create a new file under a empty folder with proper matching name.
  • Then you can zip it
  • Upload it

TIPS 💡

• How Do I Upload All Test Cases at Once?
• For creating arrays input give spacing properly.
• For boolean output give 1 or 0.

DSL 🧠

Welcome to HackerRank DSL (Domain Specific Language) Documentation! You can use our the DSL to generate code stubs that read test case data from standard input in hackerrank challenges.

• Datatypes Supported
• Reading Variables
• Writing Loops
• Reading 1-D Array
• Reading 2-D Array
• Putting Comments
• Generating Functions
• Invoke a Function
• Print a Variable
• DSL In Action
• Bug Report or Need help?

Datatypes Supported

• Integer: integer
• Float: float
• String: string
• Boolean: boolean
• Long Integer: long_integer
• Character: character

Reading variables

Writing Loops

You can use loops to read multiple test cases.

Reading 1-D Array

Note: Type is single if the array elements are on the same line. Otherwise, it should be multi.
Warning: Don't leave any extra space.

Reading 2-D Array

Putting Comments

A special comment is #StartCode, this will generate the text "your code goes here" as a comment.

Generating Functions

• Return type/Param type supported:

  • integer
  • long_integer
  • string
  • integer_array/long_integer_array/string_array
  • 2d_integer_array/2d_long_integer_array/2d_string_array (param only)
  • void (return type only)

Invoke a Function

• If the invoked function is void, return_type and variable_name should be “void”.
• If the param is a 1-d array, format is param[size]

Print a variable

• The third parameter is optional. The default separator is space. The separator can be NEWLINE, SPACE, COMMA or any character.

• Data_type supported are single integer/long_integer/string and 1-d integer/string/long_integer array.
