Race condition is a situation where multiple threads/processes access and manipulate shared data simultaneously.

• It can be eliminated by using synchronization techniques like locks, semaphores, and mutexes.

• Another way is to use atomic operations that ensure the data is accessed and modified atomically.

• Using thread-safe data structures can also prevent race conditions.

• Example: Two threads trying to increment a shared var...read more

A Singleton class is a class that can only have one instance at a time.

• It restricts the instantiation of a class to a single object.

• It provides a global point of access to that instance.

• It is often used in situations where a single object is required to coordinate actions across a system.

• Example: Database connection manager, Configuration manager, Logger manager.

Testing principles ensure software quality, while design principles guide software development.

• Testing principles include unit testing, integration testing, and acceptance testing.

Code a basic linked list

• Create a Node class with data and next pointer

• Create a LinkedList class with head pointer

• Implement methods to add, delete, and search nodes in the linked list

A circular linked list is a data structure where the last node points back to the first node, forming a loop.

• Create a Node class with data and next pointer

• Initialize the head node and set its next pointer to itself

• To add a node, create a new node and set its next pointer to the head node's next pointer, then update the head node's next pointer to the new node

Find subset of numbers in array that sum up to zero.

• Use a nested loop to iterate through all possible subsets.

• Calculate the sum of each subset and check if it equals zero.

• Store the subset if the sum is zero.

• Optimize the solution by using a hash set to store the cumulative sum of elements.

BFS (Breadth-First Search) is a graph traversal algorithm that explores all the vertices of a graph in breadth-first order.

• BFS starts at a given vertex and explores all its neighbors before moving to the next level of vertices.

• It uses a queue data structure to keep track of the vertices to be visited.

• BFS guarantees that it visits all the vertices of a connected graph.

• It can be used to find the shortest path between two
