## capitalize

### Instructions

Write a function that capitalizes the first letter of each word **and** lowercases the rest.

A word is a sequence of **alphanumeric** characters.

### Expected function

```go
func Capitalize(s string) string {

}
```

### Usage

Here is a possible program to test your function :

```go
package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Println(piscine.Capitalize("Hello! How are you? How+are+things+4you?"))
}
```

And its output :

```console
$ go run .
Hello! How Are You? How+Are+Things+4you?
$
```
