Bean annotation is used in Spring Boot on class or method to indicate that a method produces a bean to be managed by the Spring container.
Bean annotation is used on methods within a class to indicate that the method produces a bean to be managed by the Spring container.
It can also be used at the class level to indicate that the class itself is a Spring bean.
For example, @Bean annotation can be used on a method that cre...
Protected access modifier restricts interface method access to only derived or implemented classes.
Use 'protected' access modifier to restrict access to only derived or implemented classes
Protected members are accessible within the same package or by subclasses
Example: 'protected void methodName() {}' in an interface
Microservices interact with each other through APIs, messaging, or events.
Microservices communicate with each other through APIs, which can be synchronous or asynchronous.
Messaging systems like RabbitMQ or Kafka can be used for communication between microservices.
Events can be used for loosely coupled communication between microservices.
Service discovery mechanisms like Eureka or Consul help microservices locate and co...
To detect the best day to buy and sell stock in an integer array representing stock prices and days in O(N).
Iterate through the array and keep track of the minimum price seen so far.
Calculate the profit by subtracting the current price from the minimum price.
Update the maximum profit and best buy/sell days accordingly.
Return the best buy and sell days to maximize profit.
Find the next greatest number for each integer in an array in O(N) time complexity.
Iterate through the array from right to left
Use a stack to keep track of potential next greatest numbers
Pop elements from the stack that are less than the current element and update their next greatest number to the current element
Push the current element onto the stack
Repeat until all elements have a next greatest number

Fibonacci using Dynamic Programming
Use an array to store calculated Fibonacci numbers to avoid redundant calculations
Start with base cases of 0 and 1, then iterate to calculate subsequent Fibonacci numbers
Time complexity can be reduced from exponential to linear using DP
I was interviewed in Feb 2024.
