+# [Clean up after your dog](https://www.codewars.com/kata/clean-up-after-your-dog "https://www.codewars.com/kata/57faa6ff9610ce181b000028")
+
+You have stumbled across the divine pleasure that is owning a dog and a garden. Now time to pick up all the cr@p! :D
+
+Given a 2D array to represent your garden, you must find and collect all the dog cr@p - represented by `'@'`.
+
+You will also be given the number of bags you have access to (`bags`), and the capactity of a bag (`cap`). If there are no `bags` then you
+can't pick anything up, so you can ignore `cap`.
+
+You need to find out if you have enough capacity to collect all the cr@p and make your garden clean again.
+
+If you do, return `'Clean'`, else return `'Cr@p'`.
+
+Watch out though - if your dog is out there (`'D'`), he gets very touchy about being watched. If he is there you need to return `'Dog!!'`.
+
+For example:
+
+```
+bags = 2
+cap = 2
+x (or garden) =
+[[ _ , _ , _ , _ , _ , _ ],
+ [ _ , _ , _ , _ , @ , _ ],
+ [ @ , _ , _ , _ , _ , _ ]]
+```
+
+returns `'Clean'`
