Problem Description Give you a number on base ten,you should output it on base two.(0 < n < 1000)
Input For each case there is a postive number n on base ten, end of file.
Output For each case output a number on base two.
Sample Input 1 2 3
Sample Output 1 10 11
就是将一个十进制的数按二进制输出。 JAVA中直接调用Integer.toBinaryString(int i)； 以二进制（基数 2）无符号整数形式返回一个整数参数的字符串表示形式。
代码语言：javascript复制import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
while(sc.hasNext()){
int n = sc.nextInt();
System.out.println(Integer.toBinaryString(n));
}
}
}
