解题思路:

注意事项:

参考代码:

package day09;

import java.util.Scanner;

//T1464

public class Main {

public static void main(String args[]){

Scanner sc = new Scanner(System.in);

int a = sc.nextInt();

int b = sc.nextInt();

for(int i=a;i<=b;i++){

display(i);

}

}

public static void display(int n){

String s = n + "=";

//System.out.print();

for(int i=2;i<=n;i++){

if(n%i==0){

s += i+"*";

//System.out.print(i+"*");

n = n/i;

i--;

}

}

s = s.substring(0, s.length()-1);

System.out.println(s);

}

}
