1073. Adding Two Negabinary Numbers
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 ==  or arr == 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. Note: 1 <= arr1.length <= 1000 1 <= arr2.length <= 1000 arr1 and arr2 have no leading zeros arr1[i] is 0 or 1 arr2[i] is 0 or 1
