Problem 60476. Remove Adjacent Pairs

Given an array of integers where adjacent elements may be identical, your task is to remove these adjacent pairs. If removing one pair creates a new pair, continue removing pairs until no more adjacent identical elements remain.
For example, in the array [1,2,2,1,3], the adjacent pair is (2,2). After removing this pair, the resulting array is [1,1,3]. A new pair appears, (1,1). After removing this pair, the resulting array is [3].
Examples:
  1. Input: [1,2,3,3,2,4,3] Expected Output: [1,4,3]
  2. Input: [1,2,3,3,2,1] Expected Output: []
  3. Input: [2,2,2] Expected Output: [2]
  4. Input: [1,1,2,2,3,3,4,4,5,5] Expected Output: []
  5. Input: [1,1,1,2,2,3,3,4,4,5,5] Expected Output: [1]
