Answer:
O(n^2)
Explanation:
The number of elements in the array X is proportional to the algorithm E runs time:
For one element (i=1) -> O(1)
For two elements (i=2) -> O(2)
.
.
.
For n elements (i=n) -> O(n)
If the array has n elements the algorithm D will call the algorithm E n times, so we have a maximum time of n times n, therefore the worst-case running time of D is O(n^2)
<u>Output:</u>

<u>Explanation:</u>
In this snippet, the code makes use of virtual functions. A virtual function is defined as a function that is defined in the base class and redefined in the derived class. If the derived function accesses the virtual function, the program will get executed with the derived class’s version of the function.
In this code, we define the virtual function f1() in class A and also redefine it in class B which is the derived class of A. While executing the program, the function g which takes the object b (class B’s object) as a parameter. It will print class B’s version of f1() rather than class A’s version. This is working off the virtual function.
Answer:
1
Explanation:
Anything to the 0th power is 1. However, 0⁰ is undefined.
The answer is Salted Password Hashing. The process is similar to hashing., but with a twist. A random value is introduced for each user. This salt value<span> is included with the password when the hash value is calculated and is stored with the user record. Including the salt value means that two users with the same password will have different password hashes.</span>
Answer:
The answer is "False"
Explanation:
The data link layer is the protocol layer within a program, which controls data movement into a physical wireless connection. This layer is a second layer, that is also known as a collection of communications applications.
- The server network, in which many clients request, and receive service from a centralized server.
- This system provides an interface, that enables a user to request server services and view the server returns results, that's why it is wrong.
