Example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34...
The nth Fibonacci number can be calculated using recursion or iteration.
Fibonacci series has applications in computer science, mathematics, and nature.
SQL is a relational database management system, while NoSQL is a non-relational database management system.
SQL uses structured query language for defining and manipulating data, while NoSQL databases use various data models like document, key-value, graph, or wide-column stores.
SQL databases are table-based, with a predefined schema, while NoSQL databases are document-based, key-value pairs, wide-column stores, or grap...

Abstract classes in C++ are classes that cannot be instantiated and are designed to be base classes for other classes.
Abstract classes may contain pure virtual functions, making them incomplete and unable to be instantiated.
Derived classes must implement all pure virtual functions from the abstract class in order to be concrete classes.
Abstract classes can have non-virtual functions and member variables like regular cl...

This was also a technical round. He asked to optimize the code I wrote in coding round. Then he asked me a few puzzles and questions on OOPS, OS and DBMS.
Paging and segmentation are memory management techniques in operating systems.
Paging divides physical memory into fixed-size blocks called pages, while segmentation divides logical memory into variable-size segments.
Paging allows for efficient memory allocation and management, while segmentation provides protection and sharing of memory.
Paging is simpler to implement but can lead to internal fragmentation, while segmen...
Concurrency control is a technique used in databases to manage simultaneous access and modification of data by multiple users or processes.
Concurrency control ensures that transactions are executed in a way that maintains data consistency and integrity.
Techniques like locking, timestamp ordering, and optimistic concurrency control are used to implement concurrency control.
For example, in a banking system, concurrency c...
String Buffer is synchronized and thread-safe, while String Builder is not synchronized and faster.
String Buffer is synchronized, making it thread-safe for use in multi-threaded environments.
String Builder is not synchronized, resulting in faster performance but not thread-safe.
String Builder is preferred for single-threaded operations, while String Buffer is preferred for multi-threaded operations.
Smart pointers in C++ are objects that act like pointers but provide automatic memory management.
Smart pointers help prevent memory leaks by automatically managing memory allocation and deallocation.
Examples include unique_ptr, shared_ptr, and weak_ptr.
unique_ptr is used for exclusive ownership, shared_ptr for shared ownership, and weak_ptr to prevent circular references.
