关于题目是二分查找但是实际上最大数据也就是样例，java都可以秒过这档事

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int[] a = new int[1000];
        int b = sc.nextInt();
        for (int i = 1; i <= b; i++) {
            a[i] = sc.nextInt();
        }
        int c = sc.nextInt();
        for (int i = 1; i <= b; i++) {
            if (a[i] == c) {
                System.out.println(i);
                break;
            }
        }
        sc.close();
    }
}
