 ## Description
+You are given a **0-indexed** integer array `nums` of even length and there is also an empty array `arr`. Alice and Bob decided to play a game where in every round Alice and Bob will do one move. The rules of the game are as follows:
+
+- Every round, first Alice will remove the **minimum** element from `nums`, and then Bob does the same.
+- Now, first Bob will append the removed element in the array `arr`, and then Alice does the same.
+- The game continues until `nums` becomes empty.
+
+Return the resulting array `arr`.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: nums = [5,4,2,3]
+Output: [3,2,5,4]
+Explanation: In round one, first Alice removes 2 and then Bob removes 3. Then in arr firstly Bob appends 3 and then Alice appends 2. So arr = [3,2].
+At the begining of round two, nums = [5,4]. Now, first Alice removes 4 and then Bob removes 5. Then both append in arr which becomes [3,2,5,4].
