+# A wolf in sheep's clothing
+
+Wolves have been reintroduced to Great Britain. You are a sheep farmer, and are now plagued by wolves which pretend to
+be sheep. Fortunately, you are good at spotting them.
+
+Warn the sheep in front of the wolf that it is about to be eaten. Remember that you are standing at the front of the
+queue which is at the end of the array:
+
+ ```java
+ [sheep, sheep, sheep, sheep, sheep, wolf, sheep, sheep]      (YOU ARE HERE AT THE FRONT OF THE QUEUE)
+   7      6      5      4      3            2      1
+ ```
+
+If the wolf is the closest animal to you, return ```"Pls go away and stop eating my sheep".``` Otherwise, return "Oi!
+Sheep number N! You are about to be eaten by a wolf!" where ```N``` is the sheep's position in the queue.
+
+Note: there will always be exactly one wolf in the array.
+
+**Examples**
+
+Input: ```["sheep", "sheep", "sheep", "wolf", "sheep"]```
+
+Output: ```"Oi! Sheep number 1! You are about to be eaten by a wolf!"```
+
+Input: ```["sheep", "sheep", "wolf"]```
+
+Output: ```"Pls go away and stop eating my sheep"```
