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:
nums, and then Bob does the same.arr, and then Alice does the same.nums becomes empty.Return the resulting array arr.
\n
Example 1:
\n\n\nInput: nums = [5,4,2,3]\nOutput: [3,2,5,4]\nExplanation: 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].\nAt 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].\n\n\n
Example 2:
\n\n\nInput: nums = [2,5]\nOutput: [5,2]\nExplanation: In round one, first Alice removes 2 and then Bob removes 5. Then in arr firstly Bob appends and then Alice appends. So arr = [5,2].\n\n\n

Constraints:
\n\n1 <= nums.length <= 1001 <= nums[i] <= 100nums.length % 2 == 0Compiled with clang 11 using the latest C++ 20 standard.
