2733. Neither Minimum nor Maximum

Easy

Array Sorting

Problem Explanation

Explanation

To solve this problem, we can iterate through the array to find the minimum and maximum values. Then, we iterate again to find a number that is neither the minimum nor the maximum. If such a number exists, we return it; otherwise, we return -1.

We initialize min and max variables to store the minimum and maximum values.
We iterate through the array once to find the minimum and maximum values.
We iterate through the array again to find a number that is not equal to min or max.
If such a number is found, we return it; otherwise, we return -1.

Solution Code

class Solution {
    public int findNumber(int[] nums) {
        int min = Integer.MAX_VALUE;
        int max = Integer.MIN_VALUE;

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

        for (int num : nums) {
            if (num != min && num != max) {
                return num;
            }
        }

        return -1;
    }
}
