# Challenge \#11: 📹 Unwatched gifts 





EASY

The Grinch wants to steal the Christmas presents from the warehouse. To do this, he needs to know **which presents are not under surveillance**.

The warehouse is represented as an array of strings (`string[]`), where **each present (`*`) is protected if its position is next to a camera (`#`)**. Each empty space is represented with a **dot (`.`)**.

Your task is to **count how many presents are not under surveillance**, meaning they do not have any adjacent camera (up, down, left, or right).

Keep in mind: _only the 4 cardinal directions are considered "adjacent", not diagonals_.

Presents in the corners or at the edges can be unguarded, as long as they do not have cameras directly next to them.

```js
findUnsafeGifts([\
  '.*.',\
  '*#*',\
  '.*.'\
]) // ➞ 0

// All presents are next to a camera

findUnsafeGifts([\
  '...',\
  '.*.',\
  '...'\
]) // ➞ 1

// This present has no cameras around

findUnsafeGifts([\
  '*.*',\
  '...',\
  '*#*'\
]) // ➞ 2
// The presents in the top corners have no cameras around

findUnsafeGifts([\
  '.....',\
  '.*.*.',\
  '..#..',\
  '.*.*.',\
  '.....'\
]) // ➞ 4

// The four presents have no cameras, because they are diagonal to the camera
```
