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).
The strings "or 1=1" and ""or ''=''" can be commonly used to trick an SQL WHERE clause into becoming true.
So if you specify <span>' or ''=' as a password, you can log in if the query string would be:
</span><span>select username,pass from users where username='you' and password='' or ''='<span>' limit 0,1;</span></span>
