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

10
11

 

题目大意：

输出二进制.....

思路：

用的正常的方法。。

感想：

为什么这个也在动态规划中出现。。

AC代码：

#include <iostream>
#include<stdio.h>
#include<algorithm>
#include<string.h>
using namespace std;
int main()
{
long long int a,T,n,m,i,j,temp,k,b;
int arr[100005];
while(cin>>a)
{
i=0;
while(a!=0)
{
arr[i]=a%2;
a/=2;
i++;
}
for(i--;i>=0;i--)
cout<<arr[i];
cout<<endl;
}
return 0;
}
