C语言训练-求s=a+aa+aaa+aaaa+aa...a的值 （Java代码）注意下逻辑就好了

参考代码:

import java.util.Scanner;

public class Main1135 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int a = sc.nextInt();

int n = sc.nextInt();

long y = 0, S = 0;

for (int i = 1; i <= n; i++) {

y = y * 10 + a;

S += y;

}

System.out.println(S);

}

}
