Hello, Codeforces!

I'm excited to share my C++ library that can significantly improve the performance of your solutions, especially when dealing with large input and output.

https://github.com/alexmcmahonsoftware/fast-io

int x;
double y;
fin >> x >> y; // Read an integer and a double

int num = 42;
fout << "Number: " << num << fendl;

long double pi = acosl(-1);
fout << "Pi: " << fsetprecision(20) << pi << fendl;

For years, I've been using this library myself, and it consistently delivers:

• Up to 5x faster I/O on average: Solve problems quicker and avoid unnecessary timeouts.

• Blazing-fast performance for large data: Notice a 10x speedup for inputs/outputs exceeding 1MB.

But speed isn't everything! This library also prioritizes ease of use:

• Seamless integration: Simply replace cin and cout with fin and fout in your code.

• Familiar syntax: The library implements standard C++ stream operators for an intuitive experience.

• Extended Compatibility: Handles all fundamental data types and offers precision control for floating-point numbers.

I'm confident this library can be a valuable asset for you, especially when dealing with large data. While this is just the first step, stay tuned for future posts where I'll introduce more tools and techniques to help you conquer Codeforces!

Thank you.
