Write your code in main.cpp.
Once you get a problem accepted you can reset the file with git restore main.cpp.
I suggest to depend on the judging systems to keep your code.
You can also copy the file somewhere for backup before you reset it.
Works out-of-the-box on Linux because you have GCC already installed.
On Windows, I recommend a WSL and Clion setup.
On macOS you need a compiler. Try xcode-select --install for clang or brew install gcc for GCC.
You can open this repo inside a devcontainer in VSCode.
It has all the settings and compiler already installed and ready to go.
This just needs Docker and VSCode with the Dev Containers Extension.
If you want to use podman instead of docker, then dismiss the promt to install docker and change the Docker Path setting of the dev containers extension from docker to podman.
Works on all operating systems and even in the browser via GitHub codespaces!
Most modern IDEs should have CMake support. Just open this folder in your IDE. You need to have a compiler installed.
- GCC on macOS does not support sanitizers
- on ARM
long doubleis just 64 bit - the
<bits/stdc++.h>header is GCC only - prefer GCC (except on mac), because that's what most juding systems use
I enabled sanitzers for gcc and clang via CMake.
For easier debugging, set ASAN_OPTIONS=abort_on_error=1 and UBSAN_OPTIONS=abort_on_error=1.
This will open the debugger when the sanitizer finds an error.
The devcontainer already does this for you.
Clion has a settings page for these options.
Go to Settings / Preferences | Build, Execution, Deployment | Dynamic Analysis Tools | Sanitizers and put
abort_on_error=1 under AddressSanitizer and UndefinedBehaviorSanitizer.
When debugging reaches end of main the sanitizer might falsely detect an error. Ignore this.
