This repository serves as a personal space for experimentation and practice and is not representative of my professional coding standards. It primarily houses solutions to math problems, algorithms, and competitive programming exercises which I use to enhance my problem-solving capabilities.
In this context, I prioritize speed and efficiency over adherence to certain best practices such as meaningful variable naming, function reusability, and code modularity. For instance, in a competitive programming context, it's more common to use concise variables like TC or n instead of more descriptive ones like testCases or numberOfX. These solutions are not meant to be production-ready and are simply a part of my ongoing and relentless learning journey and desire to hone my problem-solving skills.
Regarding actual professional software development, I recognize and adhere to industry-standard practices for maintaining clean, efficient, and maintainable code.

To redirect the standard input and output streams from your program into a file named output.txt (works for both cout and printf):
int main()
{
std::streambuf *coutbuf = std::cout.rdbuf(); // Save old buffer
char* tempFileName = "output.txt";
std::ofstream out(tempFileName);
std::cout.rdbuf(out.rdbuf()); // Redirect std::cout to file
freopen(tempFileName, "w", stdout); // Redirect stdout to file
// ...
// (Your program here)
// ...
std::cout.rdbuf(coutbuf); // Restore the original buffer
freopen("/dev/tty", "w", stdout); // Restore stdout to the console
}

// Place your snippets for cpp here. Each snippet is defined under a snippet name and has a prefix, body and
// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the
// same ids are connected.
// Example:
// "Print to console": {

// "body": [
// "console.log('$1');",
// "$2"

// "description": "Log output to console"
