Q1. Data structures and algorithms
Add your answer
Q2. Linked list implementation
Ans. 
Linked list is a data structure where each element points to the next element in the sequence.
• Nodes contain data and a reference to the next node

• Insertion and deletion can be done efficiently

• Traversal starts from the head node

• Example: Singly linked list, Doubly linked list

Basic java questions

Q1. Explain Linked list implementation and stack
Ans. 
Linked list is a data structure where each element points to the next element. Stack is a data structure that follows Last In First Out (LIFO) principle.
• Linked list implementation involves creating nodes with data and a pointer to the next node.

• Stack implementation involves pushing elements onto the stack and popping them off in reverse order.

• Example: Linked list - 1 -> 2 -> 3 -> NULL, Stack - push(1), push(2), push(3)

Q2. Oops concepts in java
Ans. 
Oops concepts in Java refer to Object-Oriented Programming principles like Inheritance, Encapsulation, Polymorphism, and Abstraction.
• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability of a method to do different things based on the object it is acting upon.

• Abstraction: Hiding the imp...read more

MCQ on DSA, 2 simple coding question

Q1. Rotate array clockwise K times, implement binary search
Ans. 
Rotate array clockwise K times, implement binary search
• Rotate the array by reversing the array and then reversing the first K elements and then reversing the remaining elements

• Implement binary search by dividing the array into two halves and comparing the middle element with the target

• Repeat the binary search until the target is found or the array is exhausted

Q1. Implement linked list and its operations
Ans. 
A linked list is a data structure where each element points to the next element. Operations include insertion, deletion, and traversal.
• To insert a new element, create a new node and update the pointers of the previous and next nodes.

• To delete an element, update the pointers of the previous and next nodes to skip the node to be deleted.

• Traversal involves starting at the head node and following the pointers to each subse
