I applied OOPS concepts in my framework by using inheritance, encapsulation, polymorphism, and abstraction to create reusable and modular code.

• Used inheritance to create parent classes with common functionality that child classes can inherit.

• Implemented encapsulation by hiding internal implementation details and exposing only necessary methods and properties.

• Leveraged polymorphism to allow objects of different classes to be treated as objects of a common superclass.

• Utilized a...read more

Objects are instances of classes in object-oriented programming. Classes define the properties and behaviors of objects.

A program to find palindromes in a given array of strings.

• Iterate through each string in the array

• Check if the string is equal to its reverse to determine if it is a palindrome

• Store palindromes in a separate array for output

• Example: Input - ['madam', 'hello', 'level'], Output - ['madam', 'level']
