3132. Find the Integer Added to Array II

Medium

Array Two Pointers Sorting Enumeration

Problem Explanation

Explanation:

To solve this problem, we need to find the minimum possible integer x such that by removing two elements from nums1 and adding x to each element, nums1 becomes equal to nums2.

We can approach this problem by calculating the sum of elements in nums1 and nums2. Let sum1 be the sum of elements in nums1 and sum2 be the sum of elements in nums2. The difference between sum2 and sum1 divided by 2 gives us the required value of x.

Solution Code

class Solution {
    public int findIntegerAdded(int[] nums1, int[] nums2) {
        int sum1 = 0, sum2 = 0;
        for (int num : nums1) {
            sum1 += num;
        }
        for (int num : nums2) {
            sum2 += num;
        }
        return (sum2 - sum1) / 2;
    }
}
