A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.
A prime number has exactly two distinct positive divisors: 1 and itself.
Examples of prime numbers: 2, 3, 5, 7, 11, 13.
The number 1 is not prime because it has only one divisor.
The number 4 is not prime because it can be divided by 1, 2, and 4.
Design a multi-threaded framework for efficient data ingestion and processing from large files.
1. File Splitting: Divide the large file into smaller chunks for parallel processing. For example, split a 10GB file into 10 1GB chunks.
2. Thread Pool: Use a thread pool to manage a fixed number of threads for processing. This prevents overhead from creating too many threads.
3. Data Ingestion: Implement a producer-consum...
Design a URL shortener that converts long URLs into short, manageable links while ensuring efficient storage and retrieval.
Use a hash function to generate unique short codes for each URL.
Store the mapping of short codes to original URLs in a database.
Implement a redirection service that retrieves the original URL using the short code.
Consider using a custom domain for branding (e.g., 'short.ly').

There are two types of VM: process VM and system VM.
Process VM is used to run a single application and is isolated from the host system.
System VM is used to run an entire operating system and can support multiple applications.
Examples of process VM include Java Virtual Machine and .NET Framework.
Examples of system VM include VMware and VirtualBox.
Reversing a linked list involves changing the direction of the pointers in the list.
Iteratively swap the next and previous pointers of each node in the list
Recursively swap the next and previous pointers of each node in the list
Use a stack to push each node onto the stack and then pop them off in reverse order
Create a new list and iterate through the original list, adding each node to the front of the new list
Validate if a binary tree is valid or not
A valid binary tree should not have any duplicate nodes
A valid binary tree should have all left nodes smaller than the parent node and all right nodes greater than the parent node
We can use recursion to traverse the tree and check if it is valid
Spring Boot integrates Hystrix for circuit breaker patterns, enhancing fault tolerance in microservices.
Hystrix is a library that implements the circuit breaker pattern to prevent cascading failures.
In Spring Boot, you can use the @HystrixCommand annotation to define fallback methods.
Example: @HystrixCommand(fallbackMethod = 'fallbackMethod') public String riskyMethod() {...}
Hystrix provides metrics and monitoring...
It depends on the specific needs and requirements of the organization.
