What is the output of the merge function call in this program?

public class MergeExample {
    public static void merge(int[] a, int start, int mid, int end) {
        int n1 = mid - start + 1;
        int n2 = end - mid;
        int[] L = new int[n1];
        int[] R = new int[n2];
        for (int i = 0; i < n1; i++)
            L[i] = a[start + i];
        for (int j = 0; j < n2; j++)
            R[j] = a[mid + 1 + j];
        int i = 0, j = 0, k = start;
        while (i < n1 && j < n2) {
            if (L[i] <= R[j]) {
                a[k++] = L[i++];
            } else {
                a[k++] = R[j++];
            }
        }
        while (i < n1) {
            a[k++] = L[i++];
        }
        while (j < n2) {
            a[k++] = R[j++];
        }
    }
    public static void main(String[] args) {
        int[] a = {3, 27, 38, 43, 9, 10, 82};
        merge(a, 0, 3, a.length - 1);
        System.out.println(a[0] + " " + a[4]);
    }
}
