The area of a square is :math:`A_\text{s} = l^2`

The math role marks its content as mathematical notation (inline formula).
The input format is LaTeX, math syntax without the "math delimiters". The example is rendered as:
A_s = l²

After the '.. raw:: html' you can add your HTML code.
The previous HTML code is rendered as follows:

List of selected files:

Awesome! Everything worked as it should have: your code passed all the test cases. Congratulations!

Sorry, but your code failed to solve the problem. It does not solve correctly the problem you were asked for.
The output after running your code (what it prints to the screen), is different from the output the system expected.
If the administrator allowed it, you may be able to see the difference between your output and the expected output.
Tips: Read carefully what you are asked to do and check again your code.
Test your code with different inputs. You can do it in your machine or you can use the "custom input" in the tools section.

PRESENTATION ERROR

The data in your output is correct, but it is not formatted in the proper way. Check the problem statement to understand the correct format of the output.
Missing/excessive blank lines or unnecessary spaces are likely to have caused this message.

COMPILATION ERROR

Your code does not compile :/. Something is faulty in your code:
It may be a misplaced colon, bracket, quotation mark, or symbol; you may be using a reserved keyword as a variable; you may have chosen a different programming language; among other options.
The "compilation error" message includes the output that the compiler produced with the error. Read the message carefully, it is tells you what went wrong.

This means that your code failed while it was executing, which means that your code compiled but exited unexpectedly when executed.
There are many reasons why your code could crashed, some of them are:
Division by zero, invalid memory access (e.g. bad index access to an array), null pointers, among many options.

TIME LIMIT EXCEEDED

Your code exceeded the time limit. Thus, your code took too long to run the input for a given test case.
There are two options: either your code got stuck in an infinite loop or your code takes much longer than it should.
Tips: Check for infinite loops. Try to find another solution, one that takes less time to compute.

MEMORY LIMIT EXCEEDED

Getting this result means your code is using too much memory at runtime.
Tips: Check the data structures you are using, or find a more "optimal" solution, a solution that uses less memory.

OUTPUT LIMIT EXCEEDED

Getting this result means the output of your code is longer that the allowed.
Tips: Check for print expressions in a loop.

GRADING RUNTIME ERROR

Error related to notebook file submissions. This points out a runtime error while running the grading testing code.
This might be either an error in the grading code (i.e. calling non existent variable or function) or student code (i.e. the function to be tested is not present in the notebook).
Tips: Check that your code implements all that was requested with the correct signature.

If you get this message, do not worry, There's Nothing Wrong With Your Code!
This error means UNCode had a problem while running or assessing your code. So, the problem is on our side.
We apologise in advance. Please reload the page and try submitting again! If you still get the same result, please wait a while and try again or contact your professor.

SUBMISSION TIMED OUT

If you get this, it means that we had a problem running and assessing your code. Wait for a while and try to send a submission again.
This might be also caused by a too small time limit in the task configuration (talk to your professor about it).

If you get this, it means the grading environment run out of memory. There might be two possible causes:

The configured memory is to low to solve this problem (talk to your professor about it).
Your code is printing too much data, possibly caused by prints in an infinite loop.

ENVIRONMENT NOT
AVAILABLE

There was a problem while assessing your submission. Please wait a while and reload the page, and try submitting again.

Personal Data Policy

The data processing policy establishes the terms in which UNCode uses and saves the user provisioned information when using the software system. UNCode is committed to the users data security. We ensure that all the data that the owner provides to, will only be used according to the established terms in this document, and with the law 1581 of 2012.

Data processing

Personal data is collected through forms and interaction and development of tasks on the platform. The software system collect personal information as name, career, contact data as e-mail, and demographic information. Also the system collects information about each solution provided on problem as attempt state, errors type, code or notebook provided, date of submission, among others.

UNCode will execute the data processing through the collection, storage, use and circulation to:

Evaluate and grade the knowledge communicated throughout the development of the courses.
Decisions making about the pedagogical methodologies and resources used.
Monitoring, observation and study to help research processes.

Data owners rights

As the owner of your personal data, you have the following rights:

Have a free access to the provided data that have been processed.
Read, update and verify the partial, incorrect and incomplete data that may cause error or whose processing is not allowed.
Present complaints for infractions to the provisions of current regulations or have not been authorized, at the Superintendencia de Industria y Comercio.
Request the proof of the granted authorization.
Revoke the authorization and request the data deletion, while there is no legal or contractual duty that prevents them from being deleted.
Do not answer question about sensitive data. They will be optionals the answers about sensitive data, or children and adolescents data.

Requests, queries and claims attention

UNCode is that agency who is responsible for processing of the data owners to make effective their rights. You can communicate by writing to the following email

uncode_fibog@unal.edu.co

Procedure for the exercise of the Habeas Data right

For the protection of personal data, UNCode presents the following steps and minimum requirements for the exercise of your rights.

Is necessary give the following information in order to attend your request:

Complete name and last name.
Contact information.
Reason of request claim with a brief description of the right that you want to exert (consult, update, verify, revoke, delete, request proof of the granted authorization, access the data).

The max. provided term by the law to resolve your claim is fifteen (15) business days, from the day next to the date of the receipt. If it is not possible to attend the claim within these term, UNCode will inform of the reasons for the delay, and the attend date of your claim, which may not exceed eight (8) business days next to the expiration of the first term.
