1. Description

XOR Operation in an Array

2. Solution

解析：Version 1，初始值设为0，因为任何数异或0都不改变其值，按规则依次计算数组中的值，然后进行异或运算即可。

• Version 1

class Solution:
    def xorOperation(self, n: int, start: int) -> int:
        result = 0
        for i in range(n):
            x = start + 2 * i
            result ^= x
        return result
