Creating test cases for random scenarios ensures software reliability and robustness through diverse input validation.
Identify edge cases: Test with minimum and maximum input values, e.g., an empty array vs. a large array.
Use random data: Generate random inputs to simulate real-world usage, e.g., random user names or passwords.
Test invalid inputs: Ensure the system handles unexpected inputs gracefully, e.g., negative n...

Reverse a stack using recursion without using any extra space other than the internal stack space.
Use recursion to pop all elements from the original stack and store them in function call stack.
Once the stack is empty, push the elements back in reverse order.
Base case of recursion should be when the original stack is empty.

Overloading in OOP is the ability to define multiple methods with the same name but different parameters.
Overloading allows multiple methods with the same name but different parameters to coexist in a class.
The compiler determines which method to call based on the number and type of arguments passed.
Example: having multiple constructors in a class with different parameter lists.

Technical round with question based on Web Dev, Cloud Computing, Networking etc.
TELNET is a network protocol used to establish a connection with a remote computer over a network.
TELNET stands for Telecommunication Network.
It allows a user to log in to a remote computer and execute commands as if they were directly connected to that computer.
TELNET operates on port 23.
It is not secure as the data is transmitted in plain text.
SSH (Secure Shell) is a more secure alternative to TELNET.
TELNET is insecure, while SSH is secure for remote access to servers.
TELNET sends data in plain text, while SSH encrypts data for secure communication
SSH uses public-key cryptography for authentication, TELNET does not
SSH provides secure remote access to servers, TELNET does not prioritize security
TELNET operates on port 23, while SSH operates on port 22

The input sta...
Sort an array of 0s, 1s, and 2s in increasing order.
Use a three-pointer approach to partition the array into sections of 0s, 1s, and 2s.
Iterate through the array and swap elements based on their values.
Time complexity should be O(n) to meet the constraints.
Cloud computing is like renting a computer over the internet instead of owning one.
Cloud computing allows users to access and store data and applications over the internet instead of on their own physical computer.
It offers scalability, flexibility, and cost-effectiveness as users can easily adjust their storage and computing needs.
Examples include services like Amazon Web Services (AWS), Microsoft Azure, and Google Cl...
The stages in the Software Development Life Cycle include planning, design, development, testing, deployment, and maintenance.
1. Planning: Define project scope, requirements, and timelines.
2. Design: Create architecture, UI/UX, and database design.
3. Development: Write code based on design specifications.
4. Testing: Verify functionality, performance, and security.
5. Deployment: Release the software to users or clients.

of lengths N
, M
, and K
respectively, your task is to find all elements that are present in all three arrays.
The first...
Find common elements in three sorted arrays and output them in order.
Iterate through all three arrays simultaneously using three pointers.
Compare elements at pointers and move pointers accordingly.
If elements are equal, add to result and move all pointers forward.
If elements are not equal, move pointer of smallest element forward.
A volatile variable is a variable that can be modified by multiple threads simultaneously.
Volatile variables are used in multithreading to ensure visibility of changes made by one thread to other threads.
They are not cached in thread's local memory, but always read from main memory.
They are typically used for flags or status variables that are accessed by multiple threads.
Example: 'volatile boolean flag = true;'
Multithreading in Java allows multiple threads to execute concurrently, improving performance and responsiveness.
Multithreading allows multiple threads to run concurrently within a single process.
Threads share the same memory space, allowing for efficient communication and data sharing.
Java provides built-in support for multithreading through the Thread class and Runnable interface.
Example: Creating a new thread using ...
