Google Foobar Question

Problem Statement - 1

You are given two almost identical lists of worker IDs, x and y. One of the lists contains an additional ID that is not present in the other list. Your task is to write a function solution(x, y) that compares the lists and returns the additional ID.

Examples

1. Given the lists x = [13, 5, 6, 2, 5] and y = [5, 2, 5, 13], the function solution(x, y) should return 6 because the list x contains the integer 6 and the list y doesn't.

2. Given the lists x = [14, 27, 1, 4, 2, 50, 3, 1] and y = [2, 4, -4, 3, 1, 1, 14, 27, 50], the function solution(x, y) should return -4 because the list y contains the integer -4 and the list x doesn't.

public class Solution {
    public static int solution(int[] x, int[] y) {
        int xorSum = 0;

        for (int num : x) {
            xorSum ^= num;
        }
        for (int num : y) {
            xorSum ^= num;
        }

        return xorSum;
    }
}
