Class Solution
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]
andarr2[i]
are0
or1
arr1
andarr2
have no leading zeros
