The most popular languages that USACO supports are [C++11](https://en.wikipedia.org/wiki/C%2B%2B), [Java](https://en.wikipedia.org/wiki/Java_(programming_language)), and [Python 3](https://en.wikipedia.org/wiki/Python_(programming_language)). In general, we recommend the following:
- If you already know one of these languages, just use it.
- If you know multiple languages, we recommend you pick C++ over Java, and Java over Python.
- For Bronze, any language will do.
- For Silver, Gold, and Platinum, Python is not recommended.
Keep in mind that it's easy to switch languages down the road. Don't get caught up on which language to choose. Just pick the one you feel most comfortable with!
