蓝桥杯算法提高VIP-乘法运算-题解（Java代码）

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

        Scanner scanner=new Scanner(System.in);

        int m=scanner.nextInt();

        int n=scanner.nextInt();

System.out.printf("%4d",m);

System.out.println();

System.out.printf("×%2d",n);

System.out.println();

System.out.println("━━━");

if(n>=10) {

int a=n%10*m;

int b=n/10*m;

if(a==0)

System.out.print("  00");

else

System.out.printf("%4d",a);

System.out.println();

System.out.printf("%3d",b);

System.out.println();

System.out.println("━━━");

System.out.printf("%4d",b*10+a);

}

else

System.out.printf("%4d",m*n);

}

}
