Given array of integers, find Maximum difference between two elements such that larger element appears after the smaller number.

```
int arr[]={14, 12, 70, 15, 95, 65, 22, 30};
Max Difference =95-12 = 83
```

public static int calculateMaxDifferenceBetweenTwoElements(int[] arr) { int minElementTillNow=arr[0]; int maxDifference=Integer.MIN_VALUE; for (int i = 0; i < arr.length; i++) { int difference=0; if(arr[i] >minElementTillNow) { difference=arr[i]-minElementTillNow; if(difference > maxDifference) { maxDifference=difference; } } else { minElementTillNow=arr[i]; } } return maxDifference; }
