解题思路:





注意事项:





参考代码:

import java.util.Scanner;

public class A1047 {

public static void main(String args[]) {

Scanner sc = new Scanner(System.in);

int a = sc.nextInt();

int b[] = new int[a];

int n = 0;

loop: for (;;) {

for (int i = 0; i < b.length; i++) {

if (b[i] == 0)

n++;

if (n % 3 == 0) {

b[i] = 1;

n = 0;

}

int s = 0;

for (int x = 0; x < b.length; x++) {

if (b[x] == 0)

s++;

}

if (s == 1) {

for (int x = 0; x < b.length; x++) {

if (b[x] == 0) {

System.out.println(x+1);

break loop;

}

}

}

}

}

}

}
