3371. Identify the Largest Outlier in an Array

Medium

Array Hash Table Counting Enumeration

Problem Explanation

Explanation

To identify the largest potential outlier in the given array, we can first calculate the sum of all elements in the array. Then we find the maximum and minimum values in the array. The sum of special numbers can be calculated by subtracting the maximum and minimum values from the total sum. The potential outlier would be the element that is not equal to the sum of special numbers, maximum value, or minimum value.

First, calculate the total sum of all elements in the array.
Find the maximum and minimum values in the array.
Calculate the sum of special numbers by subtracting the maximum and minimum values from the total sum.
Iterate through the array to find the potential outlier.

Time complexity: O(n) where n is the number of elements in the array. Space complexity: O(1) as we are using a constant amount of extra space.

Solution Code

class Solution {
    public int largestOutlier(int[] nums) {
        int totalSum = 0;
        int maxVal = Integer.MIN_VALUE;
        int minVal = Integer.MAX_VALUE;

        for (int num : nums) {
            totalSum += num;
            maxVal = Math.max(maxVal, num);
            minVal = Math.min(minVal, num);
        }

        int specialSum = totalSum - maxVal - minVal;

        for (int num : nums) {
            if (num != specialSum && num != maxVal && num != minVal) {
                return num;
            }
        }

        return -1; // No outlier found
    }
}
