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
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

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Start from the first element and compare it with the next element
If the next element is smaller, swap them
Repeat this process for all elements in the array
Continue this process until no more swaps are needed
A program to print all prime numbers
Take input from user for range of numbers
Loop through the range and check if each number is prime
Print the prime numbers
Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.
Hashmap uses a hash function to map keys to indices in an array.
Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add new properties and methods.
