    Java solution - passes 100% of test cases

    O(n) runtime achieved by keeping track of minimum and maximum values.

    From my HackerRank solutions.

    class Difference {
    private int[] elements;
    public int maximumDifference;
    Difference (int [] elements) {
        this.elements = elements;
    }

    void computeDifference() {
        int min = elements[0];
        int max = elements[0];
        for (int num : elements) {
            min = Math.min(min, num);
            max = Math.max(max, num);
        }
        maximumDifference = max - min;
    }
} // End of Difference class
