The first question is about a single linked list problem, and the second question is about substring matching.
For the single linked list problem, you may need to implement operations like insertion, deletion, and traversal.
For substring matching, you can use algorithms like brute force, Knuth-Morris-Pratt, or Boyer-Moore.
Examples for the single linked list problem: reversing a linked list, finding the middle element, o...

It enabled features like SMS, MMS, and basic internet browsing.
Examples of 2G technologies include GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access).
3G technology refers to the third generation of mobile telecommunications technology, offering faster data transfer speeds and improved network capacity.
3G technology allows for faster internet browsing and multimedia streaming on mobile devices
It enables video calling and mobile TV services
Examples of 3G technologies include UMTS (Universal Mobile Telecommunications System) and CDMA2000
4G technology is the fourth generation of mobile telecommunications technology, offering faster data speeds and improved network reliability.
4G stands for fourth generation and is the successor to 3G technology
Provides faster data speeds for browsing, streaming, and downloading
Offers improved network reliability and coverage compared to previous generations
Supports advanced features like VoLTE (Voice over LTE) and vide...
5G technology is the fifth generation of mobile networks, offering faster speeds, lower latency, and increased capacity for wireless communication.
5G technology provides faster download and upload speeds compared to 4G LTE.
It has lower latency, meaning less delay in data transmission.
5G networks can support more devices simultaneously, making it ideal for IoT applications.
It enables new technologies like self-driving c...
TCP/IP is a set of rules governing the exchange of data over the internet.
TCP/IP stands for Transmission Control Protocol/Internet Protocol.
It is a suite of communication protocols used to connect devices on the internet.
TCP ensures that data is delivered reliably and in order.
IP is responsible for addressing and routing data packets.
Examples of TCP/IP applications include web browsing, email, and file transfer.

Multi-processing involves running multiple processes simultaneously, while multi-threading involves running multiple threads within a single process.
Multi-processing allows multiple processes to run concurrently, each with its own memory space and resources.
Multi-threading allows multiple threads to run within the same process, sharing the same memory space and resources.
Multi-processing is typically used for CPU-bound...
Yes, we can declare the constructor private in a class.
Yes, we can declare the constructor private to prevent instantiation of the class from outside.
Private constructors are commonly used in singleton design pattern implementations.
Example: private MySingleton() {}
Polymorphism is the ability of a single function or method to operate on different types of data.
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: Inheritance in object-oriented programming languages like Java allows for polymorphism.
