<p><a href="https://ce.judge0.com">Judge0</a> is a robust, scalable, and <a href="https://github.com/judge0/judge0">open-source</a> <strong>online code execution system</strong>. You can use it to build a wide range of applications that need online code execution features. Some examples include competitive programming platforms, e-learning platforms, candidate assessment and recruitment platforms, online code editors, online IDEs, and many more.</p>
<p>In our research paper <a href="https://paper.judge0.com">Robust and Scalable Online Code Execution System</a>, we present Judge0’s modern modular architecture that can be easily deployed and scaled. We study its design, comment on the various challenges in building such systems, and compare it with other available online code execution systems and online judge systems.</p>
<p>To see Judge0 in action, try <a href="https://ide.judge0.com">Judge0 IDE</a> - our free and open-source online code editor. You can also try using a <a href="/dummy-client.html">dummy client</a> that can help you explore and test most of the features of Judge0.</p>

<h3 id="header-single-file-programs-and-multi-file-programs">Single-file programs and multi-file programs <a class="permalink" href="#header-single-file-programs-and-multi-file-programs" aria-hidden="true"></a></h3>
<p>Judge0 can run both single-file and multi-file programs in a sandboxed environment with specified resource limitations.
The usage of multi-file programs is slightly different from single-file programs and this section explains their differences and when they should be used.</p>
<h4 id="header-single-file-programs">Single-file programs <a class="permalink" href="#header-single-file-programs" aria-hidden="true"></a></h4>
<p>This is the simplest way to run a program with Judge0. Pick a <a href="#statuses-and-languages-language-get">language</a> with <code>language_id</code>, provide a <code>source_code</code> and Judge0 will use predefined compilation and execution scripts for specified language. Additionally you can set custom compile flags, provide command line arguments and send <code>additional_files</code> that will be available in the sandbox alongside your single-file program.</p>
<p>With <code>additional_files</code> you can send, for example, Python modules which are imported by your main program that you provided in <code>source_code</code> attribute. For C or C++ programs with <code>additional_files</code> you can send header files which are included by your main program that you provided in <code>source_code</code> attribute.</p>
<p>Even though you can send and use multiple Python modules or C and C++ header files, we call this <em>single-file programs</em> because for compiled languages only <strong>one</strong> source file is compiled with predefined compilation scripts.</p>
<h4 id="header-multi-file-programs">Multi-file programs <a class="permalink" href="#header-multi-file-programs" aria-hidden="true"></a></h4>
<p>Multi-file programs are available since <a href="https://github.com/judge0/judge0/tree/v1.10.0">v1.10.0</a> and they allow you specify your own compilation and execution scripts that Judge0 will use.</p>
<p>To use multi-file program feature you need to choose a language called <em>Multi-file program</em> whoose ID is <strong>89</strong>. Moreover, you need to send all program files with <code>additional_files</code> attribute. With multi-file programs attribute <code>source_code</code> cannot be used, i.e. all files should be sent with <code>additional_files</code> attribute.</p>
<p>As mentioned in the table above, <code>additional_files</code> attribute should be a content of a Base64 encoded <code>.zip</code> archive. This archive will be extracted in the sandbox before compilation and execution.</p>
<p>For the Judge0 to know how to compile and execute your multi-file program you need to provide two special files that should be available in the root of the <code>.zip</code> archive that you are sending with <code>additional_files</code> attribute. These files should be named <code>compile</code> and <code>run</code>, and are expected to be Bash scripts that know how to compile and execute your multi-file program. If your multi-file program does not need compilation step, then you don’t need to provide <code>compile</code> script. Take a look at <a href="https://github.com/judge0/examples/tree/master/cpp-and-cmake-01">this example</a> to learn how to use this feature to compile and run multi-file C++ project that uses CMake.</p>
<div id="submissions-submission-post" class="action post"><h4 class="action-heading"><div class="name">Create a Submission</div><a href="#submissions-submission-post" class="method post">POST</a><code class="uri">/submissions/{?base64_encoded,wait}</code></h4><p>Creates new submission. Created submission waits in queue to be processed. On successful
creation, you are returned submission token which can be used to <a href="#submissions-submission-get">check submission status</a>.</p>
<p>If submission’s <code>source_code</code>, <code>stdin</code> or <code>expected_output</code> contains non printable characters, or
characters which cannot be sent with JSON, then set <code>base64_encoded</code> parameter to <code>true</code> and
send these attributes Base64 encoded. Your responsibility is to encode each of mentioned attributes
(<code>source_code</code>, <code>stdin</code> and <code>expected_output</code>) even if just one of them contains non printable
characters. By default, this parameter is set to <code>false</code> and Judge0 assumes you are sending plain text data.</p>
<p>By default you are returned submission token on successful submission creation. With this token you can <a href="#submission-submission-get">check submission status</a>.
Instead of checking submission status by making another request, you can set the <code>wait</code> query parameter to <code>true</code> which will enable you to get submission status immediately as part of response to the request you made.
Please note that this feature may or may not be enabled on all Judge0 hosts. So before using this feature please check <a href="#system-and-configuration-configuration-info-get">configuration</a> of Judge0 you are using. On an <a href="https://api.judge0.com">official Judge0</a> this feature <strong>is not</strong> enabled.</p>

<p>Please note that Judge0 consists of two systems: <strong>web</strong> and <strong>worker</strong>. <strong>Web</strong> system is the one who
provides you the web API, and <strong>Worker</strong> is the one who processes your submissions. They can be placed on two or more
different hosts with different system configurations. Result of this API request is always from web system.
This means that this request might be irrelevant to you if you as user don’t know if web and worker are

file by admin who hosts Judge0 instance.</p>
<p>This configuration gives every admin a flexibility to configure Judge0 according to server abilities and needs. It also gives users
insight on some <em>default configuration values</em> which are used when their programs are run.</p>
<p>Each of these <em>configuration variables</em> have <em>default values</em> which we consider as recommended in case you are not sure should you change them.</p>
<p>We will refer to <em>default values</em> as values which Judge0 automatically assigns to each of these <em>configuration variables</em>,
if admin didn’t set them. For example, default value of <em>configuration variable</em> <code>cpu_time_limit</code> is <code>2</code>.</p>

<p><em>Default configuration value</em> for each variable is given to you as response of this API call. For example, <em>default configuration value</em>
for variable <code>cpu_extra_time</code> might be <code>2</code>, and if admin didn’t set this, then it is <code>0.5</code> (<em>default value</em>).
This means that admin set <code>cpu_extra_time</code> <em>configuration variable</em> to value <code>2</code> and we say it is now <em>default configuration value</em> for this
variable <code>cpu_extra_time</code>.</p>
<p>Every <a href="#submissions-submission">submission</a> can change each of the configuration variables according to its needs. For example,
user might create submission which has <code>cpu_time_limit</code> of <code>5</code> seconds. For security reasons we need to limit values of each of these
configuration variables. For example, we don’t want user to create a submission which has <code>cpu_time_limit</code> of <code>100000</code> seconds.</p>
<p>For this security reason we are introducing <em>limit configuration variables</em> for each <em>configuration variable</em>.</p>
