<span>If using excel, you can use this formula:
DATEDIF(start_date, end_date, unit)
For instance,
DATEDIF(9/1/2014, today, "d")
or
DATEDIF(B10, today, "d")</span>
Answer:
B.O(n).
Explanation:
In an ADT graph the method addEdge uses an Array of list.So in the worst case and the worst will be when the list already has n elements in it.
So to add an edge we have to iterate over the list upto nth element and then add the edge after that.So it has to travel over n elements.
So we can say that the answer is O(n).
