Getting started

Prerequisites

• A C++ compiler that supports C++17/C++20 (g++, clang++)
• Optional: CMake (>=3.10) for multi-file projects
• Optional: clang-format for consistent formatting
• Unix-like shell (Linux, macOS, WSL) or Windows with suitable toolchain

Build & run (single file)

Compile a single solution file with g++:

# compile
g++ -std=c++20 -O2 -Wall -Wextra problems/2025-01-01-example/solution.cpp -o bin/example

# run
./bin/example < problems/2025-01-01-example/input.txt
