Pseudo code for circular queue
A circular queue is a data structure that follows the FIFO (First-In-First-Out) principle.
It uses an array to store the elements and two pointers, front and rear, to keep track of the queue.
When the rear pointer reaches the end of the array, it wraps around to the beginning, creating a circular behavior.
To enqueue an element, check if the queue is full. If not, increment the rear pointer a...
Concatenation of linked lists is the process of combining two or more linked lists into a single linked list.
Create a new linked list to store the concatenated result.
Traverse the first linked list and add each node to the new linked list.
Traverse the second linked list and add each node to the new linked list.
The last node of the first linked list should point to the head of the second linked list.
Return the head of t
Finding the intersection point of two linked lists.
Traverse both lists and find their lengths.
Move the pointer of the longer list ahead by the difference in lengths.
Now, traverse both lists simultaneously until the pointers meet.
The meeting point is the intersection point.
To find the height of a tree and its mirror image, we need to traverse the tree and calculate the maximum depth.
Traverse the tree using depth-first search or breadth-first search
Keep track of the maximum depth encountered during traversal
Repeat the traversal process for the mirror image of the tree
Compare the heights of the original tree and its mirror image
Inheritance in everyday life is when traits or characteristics are passed down from parents to children.
Inheritance in code allows a class to inherit properties and methods from another class.
In everyday life, children often inherit physical traits, such as eye color or height, from their parents.
In code, a child class can inherit attributes and behaviors from a parent class.
For example, a parent class 'Animal' can hav...

The 4 principles of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation restricts access to certain components within a class, protecting the data.
Abstraction hides complex implementation details and only shows the necessary features.
Polymorphism allows objects to be treated as instances of their parent class.
String buffer is synchronized and thread-safe, while string builder is not synchronized and faster.
String buffer is synchronized, making it thread-safe for use in multi-threaded environments.
String builder is not synchronized, providing better performance in single-threaded applications.
String builder is faster than string buffer due to lack of synchronization overhead.
Example: StringBuffer sb = new StringBuffer(); Str
Strings are immutable in order to ensure data integrity and security.
Immutable strings prevent accidental data modification, ensuring data integrity.
Immutable strings enhance security by preventing unauthorized access or tampering.
Immutable strings allow for more efficient memory management and optimization.
Example: 'Hello' cannot be changed to 'Hella' directly, a new string must be created.
There are two types of exceptions in Java: checked exceptions and unchecked exceptions.
Checked exceptions are checked at compile time and must be handled using try-catch or throws keyword.

Examples of checked exceptions include IOException, SQLException, and ClassNotFoundException.
Examples of unchecked exceptions include...
