Q1. Pillars of Object Oriented Programming. Real Life Example of Pillars of OOPS.
Ans. 
Pillars of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism. Real life example: Vehicles.
• Inheritance: Car and Bike classes inheriting from Vehicle class.

• Encapsulation: Data hiding in a class to protect it from outside interference.

• Abstraction: Using a remote control to operate a TV without knowing its internal workings.

• Polymorphism: Overloading a method with different parameters in a class.

Q2. Is Function Overloading the Only Example of Compile Time Polymorphism ?
Ans. 
No, Function Overloading is not the only example of Compile Time Polymorphism.
• Function Templates are another example of Compile Time Polymorphism where a single function can operate on different data types.

• Operator Overloading is also an example of Compile Time Polymorphism where operators can be overloaded to work with different data types.

• Static Polymorphism achieved through method overloading is another example of C

Q3. Difference Between Arrays and LinkedLists. Cons and Pros of Using Them. Which Out of Both Would be Preferable in Different Situations ?
Ans. 
Arrays store elements in contiguous memory locations, while LinkedLists store elements in nodes with pointers to the next element.
• Arrays have constant time access to elements using index, while LinkedLists have O(n) access time as they need to traverse from the beginning.

• Arrays have fixed size, while LinkedLists can dynamically grow and shrink in size.

• Arrays are better for random access and search operations, while Lin...read more

Q4. Creating LinkedList Class , Insertion and Deletion in a LinkedList , Reversing and Sorting a LinkedList , Questions on Circular Linked List.
Ans. 
Answering questions related to LinkedList operations and Circular LinkedList.
• LinkedList Class: Implement a class with nodes containing data and a reference to the next node.

• Insertion: Add a new node at the beginning, end, or at a specific position in the LinkedList.

• Deletion: Remove a node by updating references to skip over it.

• Reversing: Traverse the LinkedList and reverse the links between nodes.

• Sorting: Implement a s...read more

Q6. Reverse a String without Using Any Loop or Using Any Other Data Structure.
Ans. 
Use recursion to reverse the string without using loops or other data structures.
• Create a recursive function that takes the string as input.

• In the function, check if the string is empty or has only one character, return the string in that case.

• Otherwise, call the function recursively with the substring excluding the first character and concatenate the first character at the end.

Q7. Program to Find the Maximum Occurring Number in an Array. Which Data Structure can be Used for Making the Code More Efficient ?
Ans. 
Use a hashmap to store frequency of each number in the array for efficient retrieval of maximum occurring number.
• Use a hashmap to store the frequency of each number in the array.

• Iterate through the array and update the frequency count in the hashmap.

• Find the number with the highest frequency in the hashmap to get the maximum occurring number.

Q8. What is Multi-Threading in Java ? What are Generics ?
Ans. 
Multi-Threading in Java allows multiple threads to execute concurrently. Generics in Java enable type-safe collections and classes.
• Multi-Threading in Java allows for concurrent execution of multiple threads.

• Generics in Java enable type-safe collections and classes by allowing the use of parameterized types.

• Example of Multi-Threading: creating a new thread using the Thread class and implementing the run() method.

• Example...read more

Q2. What is TCP, UDP, Difference between TCP and UDP, Three way handshaking problem, socket programming, HTTP Protocol.
Ans. 
TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are protocols used for data transmission over networks.
• TCP is a connection-oriented protocol that guarantees reliable delivery of data.

• UDP is a connectionless protocol that does not guarantee reliable delivery of data.

• The main difference between TCP and UDP is that TCP provides reliable, ordered, and error-checked delivery of data, while UDP does not.

• Use a map to store the horizontal distance and the bottom-most node at that distance.

• Traverse the tree in level order and update the map with each node's horizontal distance and level.

• Print the nodes in the map in ascending order of their horizontal distance.

Q1. Is circular loop is there in a linkedList
Ans. 
No, a circular loop is not present in a linked list.
• A linked list does not have a circular loop by default.

• If a linked list has a circular loop, it is considered a circular linked list.

• Circular linked lists can be detected using Floyd's Cycle Detection Algorithm.

Q2. How to identify the duplicates in circular linkedList
Ans. 
To identify duplicates in a circular linked list, use a hash set to keep track of visited nodes.
• Traverse the circular linked list while adding each node to a hash set.

• If a node is already in the hash set, it is a duplicate.

• Consider edge cases such as an empty list or a list with only one node.

Q2. Oops concepts explain with examples
Ans. 
Oops concepts are fundamental principles of object-oriented programming.
• Encapsulation: bundling data and methods that operate on the data into a single unit (class)

• Inheritance: allows a class to inherit properties and behavior from another class

• Polymorphism: ability to present the same interface for different data types

• Abstraction: hiding the complex implementation details and showing only the necessary features
