## Binary

View as PDFYour computer science teacher has kindly requested that you write a program to convert a number, inputted in decimal, to binary to help in teaching students about binary. Also to aid in human processing of numbers, you should group every four bits and separate the groups by space.

#### Input Specification

The first line will be integer (), the number of numbers to convert to binary. The next lines will be such that ().

#### Output Specification

For every integer , output the binary representation, grouped into four bit groups, separated by spaces. If necessary, you must pad the first group to have exactly four bits.

#### Sample Input

```
3
1
10
255
```

#### Sample Output

```
0001
1010
1111 1111
```

## Comments

Java has a method you can call against the Integer class: Integer.toBinaryString(number);

Note the output specification: (1) 16 --> 10000,output should be:

0001 0000,output should not be:1000 0 (2) 0 --> 0000,1 --> 0001, 7 --> 0111

what is the output if the input is 0

I tested my solution using eclipse and all the test cases are correct, why am I getting WA in my submissions?

UPDATE: Nvm, I was making a stupid mistake

I can't get the first text case to work...is anyone having a similar problem?

It seems that im getting the right answers, but im still getting wa. Is there anything wrong with how i'm using sys.stdout.write?

There is more than one input.
