Task

Create and display the sequence of binary digits for a given   non-negative integer.

```
   The decimal value      5   should produce an output of               101
   The decimal value     50   should produce an output of            110010
   The decimal value   9000   should produce an output of    10001100101000

```

The results can be achieved using built-in radix functions within the language   (if these are available),   or alternatively a user defined function can be used.

The output produced should consist just of the binary digits of each number followed by a   *newline*.

There should be no other whitespace, radix or sign markers in the produced output, and leading zeros should not appear in the results.

```
say .fmt("%b") for 5, 50, 9000;
```

```
101
110010
10001100101000

```

Alternatively:

```
say .base(2) for 5, 50, 9000;
```

```
101
110010
10001100101000
```
