2 Consider the sequence of keys (5,16,22,45,2,10,18,30,50,12,1). Draw the result of inserting entries with these keys (in the gi
Juliette [100K]
Answer:
A) (2,4) tree
- Insertion of key 45 makes key unbalanced and this is because it violates the 2,4 tree so we split the node
- insertion of key 10 makes key unbalanced and this is because it violates the 2,4 tree so we split the node
B) Red-black tree
Explanation:
The diagrams for the solutions are attached showing the results of inserting entries
Answer:
- var today = new Date();
- var dateComp = [];
- dateComp[0] = today.getDate();
- dateComp[1] = today.getMonth();
- dateComp[2] = today.getFullYear();
-
- switch(dateComp[1]){
- case 0:
- console.log("Jan " + dateComp[0] + "," + dateComp[2])
- break;
- case 1:
- console.log("Feb " + dateComp[0] + "," + dateComp[2])
- break;
- case 2:
- console.log("Mar " + dateComp[0] + "," + dateComp[2])
- break;
- case 3:
- console.log("Apr " + dateComp[0] + "," + dateComp[2])
- break;
- case 4:
- console.log("May " + dateComp[0] + "," + dateComp[2])
- break;
- case 5:
- console.log("Jun " + dateComp[0] + "," + dateComp[2])
- break;
- case 6:
- console.log("Jul " + dateComp[0] + "," + dateComp[2])
- break;
- case 7:
- console.log("Aug " + dateComp[0] + "," + dateComp[2])
- break;
- case 8:
- console.log("Sept " + dateComp[0] + "," + dateComp[2])
- break;
- case 9:
- console.log("Oct " + dateComp[0] + "," + dateComp[2])
- break;
- case 10:
- console.log("Nov " + dateComp[0] + "," + dateComp[2])
- break;
- case 11:
- console.log("Dec " + dateComp[0] + "," + dateComp[2])
- break;
- }
Explanation:
The solution code is written in JavaScript.
Firstly, create a Date object (Line 1). The date object will automatically capture the current date and time.
Next create an array dateComp to hold the day, month and year (Line 3 -5). We use the getDate method to get current day, getMonth method for current month and getFullYear method for current year.
This is important to note that the getMonth method will return the value range from 0 - 11 with the Jan is represented as 0, Feb is 1 and so forth. Presume we intend to display the date using the format "month day, year", we can create a switch structure to check the month value which is range from 0 to 11. If month value is 0, generate string Jan + current day + "," + current year. We generate the date string based on different switch cases (7 - 44). We shall see the output similar to the date string as shown below:

Answer:</h2>
Authorization specifies what a user can do, and access control enforces what a user can do.
<h2>
Explanation:</h2>
Authorization is simply granting access to an authenticated user of an application. It specifies what a user can and/or cannot do. For example, for a user to access their banking details in an online banking service, they have to be authorized by first authenticating them to prove their identity. Another example is in an organizational system where some users (normally called admins) can access certain database info whereas some other users (normally called the regular users) cannot.
Access control is used to enforce the policies dictated by authorization. In other words, access control enforces the policy of what a user can and/or cannot do. Access control makes authorization possible. It is sometimes called privileges or permissions. For example, the <em>security tab </em>in the operating system of Windows, allow to set access privileges for certain files and/or folders. Another example is in an organizational system where some files on the organization's server are configured in such a way that access to it is restricted and dependent on some further authorization.
