✨ Competitive Programming Template ✨

Hello fellow programmer! Welcome to the Awesome Competitive Programming Template GitHub repository. 🚀 This repository is your go-to destination for a comprehensive and handy competitive programming template written in C++. Whether you're a seasoned coder or just getting started, this template is designed to supercharge your problem-solving skills! 🏆

Table of Contents 📚

Introduction 🌟

Hey there, future coding champion! 🎉 Competitive programming is like a puzzle-solving adventure. 🧩 Our template is your trusty sidekick to tackle those algorithmic challenges head-on!

homepage Ideal Setup for Quick Run and Debug

Getting Started 🚀

Excited to dive in? It's simple! Copy the amazing C++ code provided in this repository and paste it into your favorite C++ development environment or online compiler. Voilà! You've got the power of the template at your fingertips. 💪

runner Add Test Case in Input File and Hit CTRL + R to Run

🚀 Macros

  • FastIO: Speed up your input/output operations with this magical macro.
  • el: Say bye-bye to '\n'! Use this instead for a friendly newline.
  • MOD1 and MOD2: Ready-to-use modular constants for those modulo calculations.
  • INF: Your personal "infinity" for comparisons. 🌌

📦 Container Macros

  • all(x): Wrangle your containers with ease, get the full range.
  • rall(x): Reverse the fun! Go from end to start in a snap.
  • popFront(x): Bye-bye first element! Remove it from your container.
  • mp(x, y): Create a magical pair with values x and y.
  • pb(x): Push x into your container (e.g., vector), like a pro.
  • ppb(x): Pop the last element from your container, with flair.

🔖 Typedefs

  • ll: Short for long long int - your trusty big integer friend.
  • ull: Say hi to unsigned long long int for all those positive vibes.
  • lld: For precise calculations with a touch of decimal magic.
  • vl: An abbreviation for vector<ll> - your versatile list.
  • vll: It's like vl, but each element is a pair. Cool, right?
  • pll: Say hello to pair<ll, ll> - two values in one! 🤝

🔍 Debug Utilities

Noticed a pesky bug? 🐞 Our debug utilities come to the rescue! These helpful tools are only active when you're not on an online judge.

  • debug(x): Peek into the value of x during debugging.
  • _print(): A bunch of overloads to print various data types and containers.
  • Operator overloads for input and output streams.

  • GCD(a, b): The magical way to find the greatest common divisor of a and b. Learn more
  • LCM(a, b): Compute the least common multiple of a and b effortlessly. Learn more
  • pwr(a, b, mod): Ace the power of a raised to b, modulo mod. Learn more
  • mminvprime(a, b): The modular multiplicative inverse of a w.r.t. prime b. Learn more
  • modAdd, modMul, modSub, modDiv: Modular arithmetic made simple! Learn more
  • isPrime(n): Unlock the secret to checking if n is prime. Learn more

Solving Problems 🤖

Ready to conquer problems? Implement the solveMyProblem function. It reads from the input stream (in) and writes solutions to the output stream (out). All neatly wrapped in a test case loop!

void solveMyProblem(istream &cin, ostream &cout, ll testCase) {
    // Your brilliant solution goes here!
}

⏱️ Time Complexity

Time is precious in competitive programming! Keep an eye on the time complexity of your solutions to ensure they're as efficient as can be.
