# Challenge \#3: 👶 Help the intern 





EASY

In Santa’s workshop there’s an intern elf who is learning to wrap gifts 🎁.

They’ve asked the elf to wrap boxes using only text… and they do it _more or less_ correctly.

They are given two parameters:

- `size`: the size of the square gift
- `symbol`: the character the elf uses to make the border (when they don’t mess it up 😅)

The gift must meet these requirements:

- It must be a **`size x size` square**.
- The inside is always empty (filled with spaces), because the elf “doesn’t know how to draw the filling yet”.
- If `size < 2`, return an empty string: the elf tried, but the gift got lost.
- The final result must be a string with newline characters `\n`.

Yes, it’s an easy challenge… but we don’t want the intern to get fired. Right?

## 🧩 Examples

```javascript
const g1 = drawGift(4, '*')
console.log(g1)
/*
 ****
 *  *
 *  *
 ****
 */

const g2 = drawGift(3, '#')
console.log(g2)
/*
###
# #
###
*/

const g3 = drawGift(2, '-')
console.log(g3)
/*
--
--
*/

const g4 = drawGift(1, '+')
console.log(g4)
// ""  poor intern…
```
