You are given a 0-indexed integer array nums whose length is a power of 2.
Apply the following algorithm on nums:
- Let n be the length of nums. If n == 1, end the process. Otherwise, create a new 0-indexed integer array newNums of length n / 2.
- For every even index i where 0 <= i < n / 2, assign the value of newNums[i] as min(nums[2 i], nums[2 i + 1]).
- For every odd index i where 0 <= i < n / 2, assign the value of newNums[i] as max(nums[2 i], nums[2 i + 1]).
- Replace the array nums with newNums.
- Repeat the entire process starting from step 1.
Return the last number that remains in nums after applying the algorithm.
