This year, we are planning to introduce problems that your submitted code can call external LLM API-s. For example, there will be a problem that, you can write the following code:

#include "llm.h"

int main(){
    string str = "Who are you?"
    string res = ask_LLM(str); // res may be equal to "Greetings! I'm DeepSeek-V3, an artificial intelligence assistant created by DeepSeek. I'm at your service and would be delighted to assist you with any inquiries or tasks you may have."
}

However, be careful enough when using such functions, because the return value and the time taken to return the answer are unpredictable.
