    Given a string 'STR' consisting solely of the characters “{”, “}”, “(”, “)”, “[” and “]”, determine if the parentheses are balanced.

    Input:

    The first line contains an...
  • Ans. 

    The task is to determine if a given string of parentheses is balanced or not.

    • Iterate through the characters of the string and use a stack to keep track of opening parentheses.

    • When encountering an opening parenthesis, push it onto the stack. When encountering a closing parenthesis, check if it matches the top of the stack.

    • If the stack is empty at the end or there are unmatched parentheses, the string is not balanced.

Round 2 - Face to Face 

(3 Questions)

Round duration - 60 minutes
Round difficulty - Easy

This was a technical and managerial round. The interviewer gave me a situation where I am in testing team and I found that customer requirement was drop down list at a place but developer has used bullet selection, and is not ready to change it. How will you manage? I gave some good replies and he was convinced.

  • Q1. What is a virtual function?
  • Ans. 

    A virtual function is a function in a base class that is declared using the keyword 'virtual' and can be overridden by a function with the same signature in a derived class.

    • Virtual functions allow for dynamic polymorphism in object-oriented programming.

    • They are used to achieve runtime polymorphism by enabling late binding.

    • Virtual functions are declared in a base class and can be overridden in derived classes.

    • Example: v...

  • Q2. Can you explain how to perform a level order traversal of a binary tree in spiral form?
  • Ans. 

    Level order traversal of a binary tree in spiral form involves alternating between left and right while traversing each level.

    • Start by pushing the root node into a queue.

    • While the queue is not empty, pop a node, print its value, and push its children into the queue.

    • For each level, alternate between popping nodes from the queue and printing their values from left to right or right to left.

    • Continue this process until all

  • Answered by AI
  • Q3. What are abstract classes in C++?
  • Ans. 

    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...

Round duration - 60 minutes
Round difficulty - Easy

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.

  • Q1. Can you explain the ACID properties in the context of database management systems?
  • Ans. 

    ACID properties are a set of properties that guarantee the reliability of transactions in database management systems.

    • ACID stands for Atomicity, Consistency, Isolation, and Durability.

    • Atomicity ensures that either all operations in a transaction are completed successfully or none of them are.

    • Consistency ensures that the database remains in a consistent state before and after the transaction.

    • Isolation ensures that the e...

  • Q2. What is the difference between paging and segmentation in operating systems?
  • Ans. 

    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...

  • Q3. What is concurrency control?
  • Ans. 

    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...

  • Q4. What is the difference between String Buffer and String Builder in Java?
  • Ans. 

    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.

  • Answered by AI
  • Q5. What are smart pointers in C++?
  • Ans. 

    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.

  • Answered by AI
  • Q6. What is the difference between a mutex and a semaphore?
  • Ans. 

    Mutex is used for exclusive access to a resource, while semaphore is used for controlling access to a resource by multiple threads.

    • Mutex is binary and allows only one thread to access the resource at a time.

    • Semaphore can have a count greater than one, allowing multiple threads to access the resource simultaneously.

    • Mutex is typically used for protecting critical sections of code, while semaphore is used for synchronizat...
