Maximum difference between two elements such that larger element appears after the smaller number | Java program to find Maximum difference between two elements such that larger element appears after the smaller number ; The function assumes that there are at least two elements in array . The function returns a negative value if the array is sorted in decreasing order . Returns 0 if elements are equal ; Driver program to test above functions ; Function calling
