两数之和：
使用cargo方便的创建rust项目：

cargo new a_plus_b
cd a_plus_b

use std::io;

fn main() {
    // Read input
    let mut input = String::new();
    io::stdin().read_line(&mut input).expect("Failed to read line");

    // Split the input into two numbers
    let numbers: Vec<i32> = input
        .split_whitespace()
        .map(|s| s.parse().expect("Parse error"))
        .collect();

    // Extract a and b
    let a = numbers[0];
    let b = numbers[1];

    // Calculate the sum
    let sum = a + b;

    // Print the result
    println!("{}", sum);
}

fn main() {
    // Simulated input
    let input = String::from("1 2"); //手造input输入

    // Split the input into two numbers
    let numbers: Vec<i32> = input
        .split_whitespace()
        .map(|s| s.parse().expect("Parse error"))
        .collect();

    // Extract a and b
    let a = numbers[0];
    let b = numbers[1];

    // Calculate the sum
    let sum = a + b;

    // Print the result
    println!("{}", sum);
}
