1486. 数组异或操作

解题思路
直接暴力模拟

代码：
java:

class Solution {
    public int xorOperation(int n, int start) {
        int num = 0;
		int sum = 0;
		for(int i = 0; i < n; i++) {
			num = start+i*2;
			sum ^= num;
		}
		return sum;
    }
}

c++:

class Solution {
public:
    int xorOperation(int n, int start) {
        int num = 0;
		int sum = 0;
		for(int i = 0; i < n; i++) {
			num = start+i*2;
			sum ^= num;
		}
		return sum;
    }
};
