**Input**

A list of words separated by any number of spaces.

**Output**

A horizontal ASCII art graph, where the n-th line is composed by as many asterisks (`*`) as the n-th word is long.

**Example usage**

The `>` signals user input, you should not input it when testing the program.

```
> This is an example histogram of word length
****
**
**
*******
*********
**
****
******

```

---

```
> a aa aaa aaaa aaaaa
*
**
***
****
*****

```

```
> double space  example
******
*****
*******

```

**Reference implementation**

In case of doubt over the specification, the output of your program should match exactly that of the below program under all inputs.

```
puts gets.chomp.split.map{|word| '*' * word.length}.join("\n")

```
