Count the frequency of characters/words and sort them based on number of occurrences in descending order.

• Split the input string into individual words

• Create a map to store the frequency of each character/word

• Sort the map based on the number of occurrences in descending order

• Return the maximum number of characters/words along with the number of occurrences

Design patterns such as microservices, retry mechanism, and bulkhead pattern are used to design a system for scalability, fault tolerance, and resilience.

• Microservices pattern involves breaking down a system into smaller, independent services that communicate through APIs.

• Retry mechanism is used to handle transient failures by automatically retrying failed operations.

• Bulkhead pattern isolates different components of a system to prevent failures in one part from affecting othe...read more

Hydraulics use fluid power to generate, control, and transmit power through the use of power packs, valves, and cylinders.

• Hydraulics use incompressible fluid to transmit power

• Power packs contain a hydraulic pump, reservoir, and motor to generate fluid flow

• Valves control the flow and direction of the hydraulic fluid

• Cylinders convert fluid power into mechanical motion

• Examples include hydraulic lifts, excavators, and braking systems

High level system design involves creating an abstract representation of the system and its components.

• Identify the system's main components and their interactions

• Determine the system's architecture and design patterns

• Consider scalability, reliability, and maintainability

• Use diagrams and models to visualize the system's structure and behavior
