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。
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)); } } }
