A palindromic substring is a string that reads the same forwards and backwards.

• Use dynamic programming to find the longest palindromic substring.

• Start by considering each character as the center of a potential palindrome.

• Expand outwards from each center to check for palindromic substrings.

• Keep track of the longest palindrome found so far.

• Example: Input 'babad', Output 'bab' or 'aba'.

The four pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction, forming the foundation of object-oriented programming.

• Encapsulation: Bundling data and methods that operate on the data within a single unit (class). Example: A class 'Car' with attributes like 'color' and methods like 'drive()'.

• Inheritance: Mechanism where a new class inherits properties and behavior from an existing class. Example: 'ElectricCar' inherits from 'Car'.

• Polymorphism: Ability t...read more
