我写的总是得不到想要的结果：我是fresh 请高手帮忙
以下是我的代码
public class div {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("please enter a integer number");
int number = in.nextInt();
StringBuffer Sb = new StringBuffer("");
Sb = Sb.append("1x");
for(int i = 2;i <number; i ++){
while(number % i == 0){
Sb = Sb.append(i + "x");
number = number / i;
}
continue;
}
System.out.println(Sb.substring(0,Sb.length()-1));
}
}
------解决方案--------------------------------------------------------
for example
- Java code
import java.util.*;public class Test { public static void main(String[] args) throws Throwable { Scanner in = new Scanner(System.in); System.out.println("please enter a integer number"); int number = in.nextInt(); List<Integer> list = new ArrayList<Integer>(); int remain = number; while (true) { boolean flag = true; for (int i=2; i<=(int)Math.sqrt(remain); i++) { if (remain%i == 0) { list.add(i); remain = remain / i; flag = false; break; } } if (flag) { list.add(remain); break; } } if (list.size() == 1) { System.out.printf("%d=1*%d\n", number, number); } else { StringBuilder buf = new StringBuilder(); buf.append(list.get(0)); for (int i=1; i<list.size(); i++) { buf.append("*").append(list.get(i)); } System.out.printf("%d=%s\n", number, buf); } }}
