机试两数之和的特别格式

要注意力扣和机试题的不同之处

import java.util.Scanner;
import java.util.*;
public class Main {
 
    public static void main(String[] args) {
        /* 辅助输入验证代码

        int n = scanner.nextInt();
        int target = scanner.nextInt();
        int [] nums = new int[n];
        for (int i = 0; i < n; i++) {
            nums[i] = scanner.nextInt();
        }
        scanner.close();
        Solution solution = new Solution();
        int [] reslut = solution.twoSum(nums, target);
        
        System.out.println("[" + reslut[0] + "," + reslut[1] + "]");

//解决函数
