Polymorphism is the ability of a function or method to behave differently based on the object it is called with.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Animal class with methods eat() and sleep(). Dog and Cat classes can inherit from Animal and override

Constructor is a special member function that initializes objects of a class.
Constructor has the same name as the class and no return type.
It is called automatically when an object is created.
It can be overloaded with different parameters.
Example: class Car { public: Car(string make, string model) { ... } };
Example: Car myCar("Toyota", "Corolla");
Operation overloading is the ability to define multiple functions with the same name but different parameters.
Allows multiple functions with the same name to perform different tasks
Functions must have different parameters or different number of parameters
Used to simplify code and improve readability
Example: + operator can be overloaded to add integers, concatenate strings, or add complex numbers
I applied via Recruitment Consultant and was interviewed before Sep 2020. There were 3 interview rounds.
A circular linked list is a linked list where the last node points to the first node.
It is a data structure where each node points to the next node and the last node points to the first node.
It can be used to implement a round-robin scheduling algorithm.
Traversal of a circular linked list requires a condition to stop the traversal, such as reaching the starting node again.

Design patterns are reusable solutions to common software design problems.
Design patterns provide proven solutions to recurring design problems in software development.
They help in creating flexible, maintainable, and scalable software.
Design patterns can be categorized into three types: creational, structural, and behavioral.
Examples of design patterns include Singleton, Observer, Factory Method, and Strategy.

The task is to determine if a given singly linked list forms a cycle or not.
A cycle occurs when a node's next points back to a previous node in the list.
To solve this problem, we can use the Floyd's Cycle-Finding Algorithm.
The algorithm uses two pointers, one moving at a normal pace and the other moving twice as fast.
If there is a cycle, the fast pointer will eventually catch up to the slow pointer.
If the fast pointer ...

The minimum depth of a binary tree is the number of nodes along the shortest path from the root node down to the nearest leaf node.
The minimum depth can be found by performing a breadth-first search (BFS) traversal of the binary tree
During the BFS traversal, keep track of the current level and increment the depth by 1 for each level
Stop the BFS traversal when a leaf node is encountered and return the depth as the minim

The problem is to find the intersection of two sorted arrays.
Use two pointers to iterate through the arrays.
Compare the elements at the current pointers and move the pointers accordingly.
If the elements are equal, add it to the intersection array and move both pointers.
If the element in the first array is smaller, move the first pointer.
If the element in the second array is smaller, move the second pointer.

A mutex is a binary semaphore used for mutual exclusion, while a semaphore is a generalized synchronization primitive.
Mutex is used to protect a critical section of code, allowing only one thread to access it at a time.
Semaphore is used to control access to a shared resource, allowing multiple threads to access it simultaneously.
Mutex has ownership, meaning the thread that locks it must unlock it.
Semaphore does not hav...
