    1486 - XOR Operation in an Array\.

    Easy

    You are given an integer n and an integer start.

    Define an array nums where nums[i] = start + 2 * i ( 0-indexed ) and n == nums.length.

    Return the bitwise XOR of all elements of nums.

    Example 1:

    Input: n = 5, start = 0

    Output: 8

    Explanation: Array nums is equal to 0, 2, 4, 6, 8 where (0 ^ 2 ^ 4 ^ 6 ^ 8) = 8. Where "^" corresponds to bitwise XOR operator.

    Example 2:

    Input: n = 4, start = 3

    Output: 8

    Explanation: Array nums is equal to 3, 5, 7, 9 where (3 ^ 5 ^ 7 ^ 9) = 8.

    Constraints:

    • 1 <= n <= 1000

    • 0 <= start <= 1000

    • n == nums.length
