1073 - Adding Two Negabinary Numbers\. Medium Given two numbers `arr1` and `arr2` in base **\-2** , return the result of adding them together. Each number is given in _array format_: as an array of 0s and 1s, from most significant bit to least significant bit. For example, `arr = [1,1,0,1]` represents the number `(-2)^3 + (-2)^2 + (-2)^0 = -3`. A number `arr` in _array, format_ is also guaranteed to have no leading zeros: either `arr == [0]` or `arr[0] == 1`. Return the result of adding `arr1` and `arr2` in the same format: as an array of 0s and 1s with no leading zeros. **Example 1:** **Input:** arr1 = [1,1,1,1,1], arr2 = [1,0,1] **Output:** [1,0,0,0,0] **Explanation:** arr1 represents 11, arr2 represents 5, the output represents 16. **Example 2:** **Input:** arr1 = [0], arr2 = [0] **Output:** [0] **Example 3:** **Input:** arr1 = [0], arr2 = [1] **Output:** [1] **Constraints:** * `1 <= arr1.length, arr2.length <= 1000` * `arr1[i]` and `arr2[i]` are `0` or `1` * `arr1` and `arr2` have no leading zeros
