In this article, we will discuss a very interesting and useful tool that can be utilized in your daily coding journey. However, it's important to note that this tool should not be used regularly as it may lead to dependency and hinder your ability to generate your own test cases and identify code problems. So, let's take a closer look at this tool and understand how it works.


Before diving into the details, it's necessary to emphasize that the tool we are discussing should be used with caution. Over-reliance on this tool may hamper your coding skills and problem-solving abilities. It should only be used in situations where you are facing difficulties and need assistance in identifying the specific test case where your code is failing.

Overview of the Tool

The tool we are talking about is designed to help you pinpoint the test case that is causing your code to fail. It works by comparing your code with a correct solution and identifying the first test case where they produce different results. This can be extremely helpful when you have tried numerous approaches and test cases but still can't figure out the problem in your code.

Downloading the Zip File

To get started with this tool, you need to download the appropriate zip file containing the necessary files. Once downloaded, extract the contents of the zip file to a suitable location on your computer.

Opening the Sample Page

Inside the extracted folder, you will find a sample folder. Open this folder and explore its contents. You will find a file named "generator.cpp" and two other codes. The "correct.cpp" file contains the correct solution, while the "wrong.cpp" file should contain the code that is failing.

Selecting the Correct Code

To use the tool effectively, select a correct submission from the list of submissions in the sample folder. It is recommended to choose a correct submission in the same programming language as your code. Copy the code from the selected submission.

Pasting the Codes

Next, open the "correct.cpp" file and paste the copied code into it. Similarly, open the "wrong.cpp" file and paste your code, which is failing, into it. This step is important for the tool to compare the correct and wrong solutions and identify the test case where they diverge.

Opening the Generator File

Locate and open the "generator.cpp" file. This file contains the specifications for the test cases that will be generated. For example, it may define the range of input values and any additional parameters required for testing.

Understanding the Test Cases

Take a closer look at the "generator.cpp" file to understand the type of test cases it will generate. It may specify the expected inputs, their limits, and any relevant variables. Make sure to set the parameters according to your requirements.

Running the Script

To execute the tool, you need to run a script provided alongside the downloaded files. Open your command line or PowerShell and navigate to the location where you extracted the files. Run the script using the appropriate command based on your installed Python version. Specify the correct solution, wrong solution, generator file, and the number of test cases you want to check.

Finding the Test Case

Wait for the script to complete its execution. It will generate random test cases and check at which point your code produces a different result compared to the correct solution. The script may take some time as it tests different cases and values. Once completed, it will provide the test case where the mismatch occurs.


In this article, we have explored a powerful tool that can be immensely helpful when debugging your code. By comparing your code with a correct solution and identifying the specific test case where they differ, you can quickly pinpoint the issue and work towards fixing it. However, it's essential to use this tool judiciously and not rely on it excessively.
