蓝桥杯基础练习VIP-分解质因数 （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 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 + "=";

        for(int i=2;i<=n;i++){

            if(n%i==0){

                s += i + "*";

                n = n / i;

                i--;

            }

        }

        System.out.println(s.substring(0,s.length()-1));

    }

}
