13. How does the total memory consumed work?

Errors during runtime: Specific test cases check for Runtime Errors (RE) only.

Yes, you can edit and submit the solution to a question (that you can view and edit) any number of times before the challenge-completion time window closes.

All inputs for the programming problems are from STDIN and output to STDOUT….

The languages that you can write code in will be mentioned in the challenge details, if applicable.

18. My submissions are not evaluated. What should I do?

When you click Submit, the code is checked extensively against internal test cases. The following parameters are considered while checking the code:

• Engineering and community Internship opportunities at HackerEarth*

Your code is tested multiple times against different input files. The displayed execution time is the total time spent executing each input file. Hence, Total execution time = (Time Limit * Number of input files)

To understand more about the judging environment, time limits, etc. you can read information about theHackerEarth judge.

Output files (generated by running your code) do not match the pre-generated output files

Check for arrays that are too large, or other elements that could grow to a size too large to fit in memory.

Some of the reasons being in such cases would be: the runtime errors mentioned above. Or, for instance usage of an external library which is causing some error, or not being used by the judge.

Yes, we recommend that you participate in oursample challenge.

An online judge is a code checker and not a human being. The code checker or judge tests your code automatically. Therefore, you must write your code accordingly.

20-01-2018 6:00 PMProblem 6 – The Simple Problem has been added to the contest.

Note: Some tests have timed sections. After the time limit is reached, you will not be able to revisit questions in that section.

Memory limit: The code should run within the give memory size otherwise it will throw a Memory Limit Exceeded (MLE) error.

This error means that your program tried to allocate memory beyond the memory limit indicated.

6th Prize (1,000 ₹): Neelesh Sinha ( NIT Jamshedpur )

However, the timer will continue running, which is why it is advised that you ensure that your computer/Internet connection is working properly before you begin the challenge.

Write code in the online code editor that is provided with each problem and submit it.

The compilation errors that you see on the screen are self-explanatory.

Output files (generated by running your code) matches all the pre-generated output files, however, it is not in the order in which the pre-generated output files are arranged

Check every single occurrence of accessing an array element and see if it could possibly be out of bounds.

We also recommend that you to viewtheseproblems from the contest that was held last year.

For each problem, based on the specifications mentioned in the problem statement, there will be one or more input files and corresponding (correct) output files. The program that you create is run on each of the input files and the corresponding output must match the (correct) output files in order.

You can submit the solution for a programming problem 300 times per day. For subjective and objective problems, you can change your answer as many times as you want.

A runtime error means that the program was compiled successfully but it crashed or exited with an error. The most common error messages include the following:

There may be an issue with the online judge due to which your submissions are not being evaluated. Send an e-mail .

5. What type of questions will I have to solve in this challenge?

31-01-2018 01:00 AMCODATHON18 was a runaway success with a registration count of over 3500 and a participation count of 3000 to back it up. In this years edition, we were able to attract such great response which speaks volumes of our mettle.

No, Time Limit Exceeded or TLE means that your solution has exceeded the amount of time that is allowed for problem execution or for a specific test case. Your solution never finished running in time and it was stopped in between. There is no definite way to know whether the code was correct.

WA means that your program ran successfully but gave an incorrect answer. This could mean either of the following:

The input file will be of the format that is specified in the problem. This means that if each input file contains multiple test cases, then your code must pass all the test cases within the specified time limit.

Your program must read, process, and output the result for all input files within the specified time limit.

Account Holder Name, Account Number, Bank, Branch, IFSC Code, Mobile Number.

It is part of the group of publicly funded institutions in India known as National Institute of Technology.

15. Does TLE error mean that my code is correct but slow?

Correct answer: If your answer is incorrect, then you will see the message Wrong Answer (WA) on the screen. This means that your program is not printing he correct answer. Ensure that your program conforms with the output format that is required.

When you click Compile & Run, the is tested against the sample input and output.

17-01-2018 9:00 PMBonus Problem – Game Of Discs will be added tonight at 10 PM IST.

4. Can we take up the challenges from mobile platforms?

6. Are the programming questions restricted to specific languages?

Ensure that you are not declaring too much stack memory. Any large arrays should be declared globally, outside of any functions – putting an array of 100000 ints inside a function probably will not work.

No. We dont support mobile platform for taking up the challenges. We only suggest our users to participate in the challenges from laptop/desktop.

9. Is it possible to change my submission after I have submitted a task?

It could happen if your program threw an exception which was not caught. Trying to allocate too much memory in a vector.

Ensure that you are not declaring too much memory. 64 MB is guaranteed, but having an array of size [100000][100000] will never work.

For example, you are accessing a[-1] in a language which does not support negative indices for an array.

10. How does the online judge determine whether a solution is correct?

This challenge enables you to understand how to participate in programming challenges on HackerEarth. It comprises detailed information about how programming questions should be attempted and details about the HackerEarth judge.

For interpreted languages like Python, NZEC will usually mean that your program either crashed or raised an uncaught exception.

This ensures that you are able to test your code against predefined sample test cases before you submit your code.

21. Why am I seeing a runtime error on the screen?

You can make multiple submissions. The platform automatically considers the best submission.

This message means that the program exited to the shell by returning a value that is different from 0.

The total memory consumed by a program is the sum of the memory that is consumed by the program in stack, data, heap, and BSS. To understand more about the address space of a program and the memory consumed, refer tothis imageorthis explanation.

For queries refer Hackerearths FAQs below.

If there is an issue with your computer or your Internet connection, you will not lose your previously submitted answers. They will be saved on HackerEarths servers. You can log in again and continue coding from where you stopped.
