Full question:
Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements and then deque 2 elements. Which indices of the internal array elements hold the remaining elements? a) 0 to 2 b) 7 to 9 c) 2 to 4 d) 1 to 3
Answer and Explanation:
If you instantiate a capacity of 10 for the queue, you have the queue a capacity of not more than 10 values.
To enqueue means to add an element to the array(if it's not full, n<10)
To dequeue means to delete an element from the array or queue(if n! =0)
From the question, for example:
We create a queue of capacity 10:
Queue q(10);
We add elements/enqueue 5 elements to the queue :
q.queueEnqueue(10);
q.queueEnqueue(5);
q.queueEnqueue(8);
q.queueEnqueue(9);
q.queueEnqueue(2);
If we print this out:
q. queueDisplay()
We would get:
10, 5, 8, 9, 2
We remove elements/dequeue 2 elements from the queue :
q. queuedequeue();
q. queuedequeue();
We print it out:
q. queueDisplay()
8 ,9, 2
We observe that deletion/dequeue starts from the front/first index.
We are left with indices 2, 3, 4 or 2 to 4
Note: the above methods/ functions and objects used are merely for example purposes. The queue uses a floating front design approach.
Ctrl(control) + s = save
Tab = auto complete formula
ctrl +c =copy'
ctrl+v = paste
ctrl +z = undo
you can also drag your formula down different cells
Answer:
I believe that the only way to really make an informed decision as to which test is a better fit for you is to take a full-length diagnostic exam for both the ACT and the SAT before doing any prep. I also would look at the pros and cons for each test.
I personally took the ACT because there is <em>NO PENALTY </em>for guessing on the test. An educated guess won't hurt your score on the ACT.
Tell someone you're close to, and see what advice they have. It's best to ignore the person until then.
It is true. RDBMS enforce integrity rules automatically. Integrity rules are automatically enforced by RDBMSs.
Integrity rules are automatically enforced by RDBMSs. Because it contains the design choices made regarding tables and their structures, a data dictionary is frequently referred to as "the database designer's database." Any character or symbol intended for mathematical manipulation may be contained in character data.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of RDBMS. Each table row in a relational database is a record with a distinct ID known as the key.
It is simple to determine the associations between data points because the table's columns carry the properties of the data and each record typically has a value for each property.
