- Easy to remember usage of codes which have not been used for long time
- Concise instruction is written directly on
.hppfiles - Less lines preferred
- Concise instruction is written directly on
- Proactively introducing non-essential codes (such as UnionFind specialized for 2D grids) for fast AC in real contests
Environments
GitHub Actions-based CI is run for the environments below:
- C++17 (GCC):
g++ -std=c++17 -O2 -Wall - C++17 (Clang):
clang++ -std=c++17 -O2 -Wall
Installation
You can easily insert the snippets using the tools such as Clipboard History and snippet-from-file
. The script generate_snippet_conf.py generates the configuration file for them.
