XOR Operation in an Array
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 = 0Output
8Array nums is equal to [0, 2, 4, 6, 8], and (0 ^ 2 ^ 4 ^ 6 ^ 8) = 8.
Example 2
Input
n = 4, start = 3Output
8Array nums is equal to [3, 5, 7, 9], and (3 ^ 5 ^ 7 ^ 9) = 8.
Constraints
- 1 <= n <= 1000
- 0 <= start <= 1000
- n == nums.length
