OOPS is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.
OOPS focuses on the concept of classes and objects
Encapsulation: bundling data and methods that operate on the data within a single unit
Inheritance: allows a class to inherit properties and behavior from another class
Polymorphism: ability to present the same interface for diffe...
Comparable is an interface used for natural ordering, Comparator is an interface used for custom ordering. Abstract class can have method implementations, Interface cannot.
Comparable interface is used to define the natural ordering of objects. Example: String class implements Comparable interface for natural ordering based on alphabetical order.
Comparator interface is used to define custom ordering of objects. Example:...

Create an array to store the count of each character
Iterate through the string and increment the count of each character in the array
Return the array with counts for each character
Remove duplicates from an array of strings

The angle between the minute and hour hand of a clock at 3:45 is 157.5 degrees.
Calculate the angle formed by the hour hand from 12 o'clock position to 3:45 position (135 degrees)
Calculate the angle formed by the minute hand from 12 o'clock position to 3:45 position (22.5 degrees)
Subtract the smaller angle from the larger angle to get the angle between the two hands (157.5 degrees)
Indexing in DBMS is a technique used to improve the performance of queries by allowing faster retrieval of data.
Indexes are data structures that store a small portion of the data set in an easily searchable format.
They help in speeding up the data retrieval process by reducing the number of disk accesses needed.
Indexes can be created on one or more columns of a table to improve the performance of SELECT queries.
Example...
The lifecycle of a React component includes mounting, updating, and unmounting phases.
Mounting phase: constructor, render, componentDidMount
Updating phase: shouldComponentUpdate, render, componentDidUpdate
Unmounting phase: componentWillUnmount

Types of joins in MySQL include inner join, left join, right join, and full join.
Inner join: Returns rows when there is a match in both tables.
Left join: Returns all rows from the left table and the matched rows from the right table.
Right join: Returns all rows from the right table and the matched rows from the left table.
Full join: Returns rows when there is a match in one of the tables.
Use a centralized API gateway to manage and route requests to multiple APIs efficiently.
Implement a centralized API gateway to handle incoming requests and route them to the appropriate API based on the endpoint.
Utilize API management tools like Apigee, Kong, or AWS API Gateway to manage and monitor multiple APIs.
Consider implementing a caching layer to improve performance and reduce the number of requests to external
