Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
It enables a single interface to be used for different data types or objects.
Examples include method overloading and method overriding in object-oriented programming.
Classes can have both implementation and state, while interfaces only have method signatures.
Classes can have constructors, interfaces cannot
Classes can have fields, interfaces cannot
A class can implement multiple interfaces, but can only inherit from one class
Example: Class 'Car' can have fields like 'color' and 'model', while Interface 'Drivable' only has method signatures like 'start' and 'stop'

Sort a given array of strings
Use built-in sorting functions in programming languages
Implement sorting algorithms like bubble sort, merge sort, etc.
Consider case sensitivity and special characters
The maximum number of repeating characters in a string needs to be determined.
Iterate through each character in the string and keep track of the count of consecutive repeating characters.
Update the maximum count whenever a new maximum is found.
Return the maximum count at the end of the iteration.
Explaining type script and java script arrow function loops with if else condition.
TypeScript and JavaScript both support arrow functions for concise syntax.
Arrow functions can be used in loops to simplify code.
If-else conditions can be used with arrow functions to add logic.
Example: const numbers = [1, 2, 3]; numbers.forEach(num => {if(num % 2 === 0) {console.log(num + ' is even');} else {console.log(num + ' is odd');
Selenium is widely used for web automation while Cypress is a newer tool with better performance and debugging capabilities.
Selenium supports multiple programming languages while Cypress only supports JavaScript.
Cypress has a built-in test runner and debugger while Selenium requires third-party tools.
Selenium is better for cross-browser testing while Cypress is better for end-to-end testing.

Q1) Write a functions to perform all CRUD in api.
Q2) Given two sorted list
ar1 =[1,2,3,4,7,7,12,18,19]
ar2 = [3, 4, 7, 7,14, 18, 19]
You can add and find largest sum but you can switch when ar1 and ar2 have same numbers.
Solution: you can base your solution on merge algo and recursively call your function to return largest sum possible.

Identifying webelement using xpath involves locating elements based on their attributes and hierarchy in the HTML structure.
Use unique attributes like id, class, name, etc. to create xpath expressions
Avoid using absolute xpaths as they are prone to breaking with changes in the HTML structure
Use relative xpaths that are more robust and flexible
Consider using xpath axes like ancestor, descendant, sibling, etc. for comple
Convert a given number to its equivalent Roman numeral representation.
Create a mapping of numbers to Roman numerals (e.g. 1 -> 'I', 5 -> 'V', 10 -> 'X', etc.)
Iterate through the mapping in descending order and subtract the largest possible numeral from the given number until it reaches 0.
Handle special cases like 4, 9, 40, 90, etc. by using subtraction rules.
Combine the Roman numerals obtained in the process to form th
