Problem Explanation

Explanation:

To find the highest difference between two salaries in an array, we can iterate through the array and keep track of the minimum and maximum salary encountered so far. At each step, we update the minimum and maximum values if we find a lower minimum or a higher maximum salary. Finally, we return the difference between the maximum and minimum salaries.

Initialize minSalary and maxSalary to the first element in the array.
Iterate through the array starting from the second element.
Update minSalary and maxSalary if a lower minimum or a higher maximum salary is found.
Calculate the difference between maxSalary and minSalary and return it.

Time Complexity:

The time complexity of this approach is O(n), where n is the number of elements in the input array.

Space Complexity:

The space complexity is O(1) as we are using a constant amount of extra space.

Solution Code

class Solution {
    public int maxSalaryDifference(int[] salaries) {
        int minSalary = salaries[0];
        int maxSalary = salaries[0];
        
        for (int i = 1; i < salaries.length; i++) {
            minSalary = Math.min(minSalary, salaries[i]);
            maxSalary = Math.max(maxSalary, salaries[i]);
        }
        
        return maxSalary - minSalary;
    }
}
