    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
