Circular, Doubly, and Doubly Circular Linked Lists
Let’s explore various linked list structures and their C++ implementations:
Node Class
The foundation of our linked lists is the Node class, representing individual elements:
#include <iostream>
using namespace std;
// Node class represents each element in the linked lists
class Node {
public:
int data;
Node* prev;
Node* next;
Node(int data) {
this->data = data;
this->prev = nullptr; Read More
Understanding Programming Concepts: From Variables to Loops
List the advantages and disadvantages of global variable. Assume the two data files “numl.Txt” and “num2.Txt” containing integers. Merge these two files to the third file named ” file3.Txt”. Here, the integers of ” file3.T-xt” must be written in sorted order. ( 2+ 8 marks)
Sure, let’s start with the advantages and disadvantages of global variables:
Advantages
1.Accessibility: Global variables can be accessed from any part of the program, making them useful for sharing data across different functions

What do you mean by Flowchart? Draw a flowchart to find the largest among three numbers entered by users. (5 marks)
A flowchart is a graphical representation of a process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. Here’s a flowchart to find the largest among three numbers entered by users:
Start
V Enter first number (num1)
V Enter second number (num2)
V Enter third number (num3)
V if num1 >= num2 and num1 >= num3 then
V Largest = num1
else if num2

Lossless Compression
Huffman-Encoding: Performing a frequency table.
-RLE (Run Length Encode): Replaces sets of repeated values for a key with a numeric indicator (3 * 2).
-LZW (Lempel-Ziv-Welch): When you find a similar sequence to another, it is replaced by a code of two values, corresponding to how many steps are reversed and how much data is repeated (101 # 32). It is used in GIF or TIFF.
Lossy Compression
.- Method fractal: Divided into blocks, scaling, rotation, we can

9: Input Domain Partitioning & Boundary Test Cases
Domain Testing
Generate test cases by assigning specific values to input variables based on analysis of the input domain.
- Input Space: x1,…,xn represents an input space where each input corresponds to a single data item. Together, they form the input vector. When the vector takes on a specific value, it is called a test point or test case.
- Input Domain: All points that are allowable input combinations.
- Sub Domain: Subset
