OOPS concepts in C++ include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: bundling data and methods that operate on the data into a single unit (class)
Inheritance: creating new classes based on existing classes, allowing for code reuse
Polymorphism: ability for objects of different classes to be treated as objects of a common superclass
Abstraction: hiding complex implementation details and sh
Multi threading is a programming concept where multiple threads run concurrently within a single process.
Multi threading allows for better utilization of CPU resources by running multiple tasks simultaneously.
Threads share the same memory space, which can lead to synchronization issues if not handled properly.
Examples of multi threading implementations include Java's Thread class, C#'s Task Parallel Library, and Python
Diamond problem occurs in multiple inheritance when a class inherits from two classes that have a common base class.
Diamond problem can be resolved using virtual inheritance in C++.
Virtual inheritance ensures that only one instance of the common base class is inherited by the derived class.
Example: class A is inherited by classes B and C, then class D inherits from both B and C. Using virtual inheritance for class A re
Types of inheritance include single, multiple, multilevel, hierarchical, hybrid, and multipath inheritance.
Single inheritance: a class inherits from only one base class.
Multiple inheritance: a class inherits from more than one base class.
Multilevel inheritance: a class inherits from a class which in turn inherits from another class.
Hierarchical inheritance: multiple classes inherit from a single base class.
Hybrid inher...

Arrow functions are more concise and have a lexical 'this' binding compared to normal functions.
Arrow functions do not have their own 'this' keyword, they inherit it from the parent scope.
Arrow functions do not have their own 'arguments' object.
Arrow functions cannot be used as constructors with 'new'.
Arrow functions are more concise and have implicit return when no curly braces are used.
forEach is used to iterate over an array and perform a function on each element, while map creates a new array by applying a function to each element.
forEach does not return a new array, while map does
forEach does not modify the original array, while map creates a new array
forEach is used for side effects, while map is used for transformation
Example: forEach - array.forEach(item => console.log(item)), map - const newAr

Iterate through each character in the array of strings and keep track of the frequency of each character. Return the character with the maximum frequency.
Create a dictionary to store the frequency of each character
Iterate through each string in the array and then through each character in the string
Update the frequency count of each character in the dictionary
Return the character with the maximum frequency
Yes, I have experience with Junit, SQL and NoSQL databases, Kafka, Dockerization, Java 8 features, stream() operations, and shell scripting in Unix.
I have used Junit for unit testing in Java projects.
SQL databases are relational databases that use structured query language for data manipulation, while NoSQL databases are non-relational databases that provide flexible schema design and horizontal scalability.
I have work...
The most complex SQL query involved nested queries for data manipulation. Used inner join. Implemented hashset and avoided trees due to their drawbacks.
Nested SQL query used for complex data manipulation
Inner join used for combining data from multiple tables
Implemented hashset for efficient data storage and retrieval
Avoided trees due to their drawbacks such as unbalanced structure and slower traversal times
Shell scripting for find and replace, adding index to lines, multithreading, hashmap vs hashtable, stack vs queue
Use sed command for find and replace in shell scripting
Use awk command to add an index at the beginning of each line in a file
Multithreading is the ability of a CPU to execute multiple threads concurrently
Single threaded means only one thread is executed at a time, while multithreaded allows multiple threads...
