Indexing a dictionary for faster search

• Use hash tables for constant time lookup

• Consider using a trie for prefix search

• Sort the keys for binary search

• Use a balanced tree for range queries

Microservices are small, independent services that communicate with each other, while monolithic is a single, self-contained application.

• Microservices are loosely coupled and can be developed and deployed independently.

• Monolithic applications are tightly coupled and require a full deployment for any changes.

• Microservices allow for better scalability and fault tolerance.

• Monolithic applications can be simpler to develop and deploy initially.

• Examples of microservices include Net...read more

Microservices are modular and scalable, while monolithic is simpler but less flexible.

• Microservices allow for independent deployment and scaling of individual components

• Monolithic architecture is easier to develop and test, but can become unwieldy as the application grows

• Microservices can be more fault-tolerant and resilient to failures

• Monolithic architecture can be more efficient for small applications with limited functionality

• Examples of microservices architecture include ...read more

Zero one knapsack problem is a classic optimization problem in computer science.

• It involves selecting a subset of items with maximum value, subject to a weight constraint.

• It is a NP-hard problem and can be solved using dynamic programming.

• Examples include packing a backpack with limited weight capacity or selecting stocks for a portfolio with limited investment budget.

The static keyword in programming is used to declare variables, methods, or classes that belong to the class itself rather than instances of the class.

• Static variables retain their values across all instances of a class.

• Static methods can be called without creating an instance of the class.

• Static classes cannot be instantiated and are used for grouping related methods and variables.

• Example: 'static int count = 0;' declares a static variable 'count' in a class.
