# Challenge \#7: 🎄 Decorating the tree 





MEDIUM

It’s time to decorate the **Christmas tree** 🎄! Write a function that receives:

- `height` → the height of the tree (number of rows).
- `ornament` → the ornament character (for example, `"o"` or `"@"`).
- `frequency` → how often (in asterisk positions) the ornament appears.

The tree is drawn with asterisks `*`, but **every `frequency` positions**, the asterisk is replaced by the ornament.

The position counting starts at 1, from the top to the bottom, left to right. If `frequency` is 2, the ornaments appear in positions 2, 4, 6, etc.

The tree must be centered and have a one-line trunk `#` at the end.

## 🧩 Examples

```javascript
drawTree(5, 'o', 2)
//     *
//    o*o
//   *o*o*
//  o*o*o*o
// *o*o*o*o*
//     #

drawTree(3, '@', 3)
//   *
//  *@*
// *@**@
//   #

drawTree(4, '+', 1)
//    +
//   +++
//  +++++
// +++++++
//    #
```
