题目描述:

将一个正整数N(1< N< 32768)分解质因数。例如，输入90，打印出90=2*3*3*5。

代码:

package lanqiao;import java.util.*;public class Main {public static void main(String[] args) {Scanner sc = new Scanner(System.in);int n = sc.nextInt();int b = 1;System.out.print(n + "=");while(n != 1){b ++;if(n % b == 0){n = n/b;if(n == 1){System.out.print(b);}else{System.out.print(b + "*");b = 1;}}}}
}
