# quadrangle

## quadA

### Instructions

Write a function `QuadA` that prints a **valid** rectangle with a given width of `x` and height of `y`.

The function must draw the rectangles as in the examples.

If `x` and `y` are positive numbers, the program should print the rectangles as seen in the examples, otherwise, the function should print nothing.

### Expected function

```go
func QuadA(x,y int) {

}
```

### Usage

Here are possible programs to test your function :

Program #1

```go
package main

import "piscine"

func main() {
	piscine.QuadA(5,3)
}
```

And its output :

```console
$ go run .
o---o
|   |
o---o
$
```

Program #2

```go
package main

import "piscine"

func main() {
	piscine.QuadA(5,1)
}
```

And its output :

```console
$ go run .
o---o
$
```

Program #3

```go
package main

import "piscine"

func main() {
	piscine.QuadA(1,1)
}
```

And its output :

```console
$ go run .
o
$
```

Program #4

```go
package main

import "piscine"

func main() {
	piscine.QuadA(1,5)
}
```

And its output :

```console
$ go run .
o
|
|
|
o
$
```

```

Program #3

```go
package main

import "piscine"

func main() {
	piscine.QuadB(1,1)
}
```

And its output :
