Java doesn't have multiple inheritance to avoid the diamond problem.

• Multiple inheritance can lead to ambiguity when two parent classes have the same method or variable.

• Java supports multiple interface inheritance to achieve similar functionality.

• Diamond problem occurs when a class inherits from two classes that have a common parent class.

• C++ supports multiple inheritance but has to use virtual inheritance to avoid the diamond problem.

Determining if a number is happy or not.

• A happy number is a number that results in 1 when replaced by the sum of the squares of its digits.

• If the sum of squares of digits results in a cycle, the number is not happy.

• For example, 19 is a happy number as 1^2 + 9^2 = 82, 8^2 + 2^2 = 68, 6^2 + 8^2 = 100, 1^2 + 0^2 + 0^2 = 1.

• To check if a number is happy or not, we can use a hash set to keep track of the numbers we have seen before.

• If we encounter a number that we have seen before,...read more

• For example, a for loop can be used to iterate over an array and perform a specific action on each element.

• Loops can also be nested, allowing for more complex iterations.

• It's important to avoid infinite loops, which can cause a pr...read more

OOPs is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPs stands for Object-Oriented Programming.

• It focuses on creating objects that interact with each other to solve a problem.

• It has four main concepts: encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation is the process of hiding data and methods within a class.

• Inheritance allows a class to inherit properties and methods from another class.

• Polymorphism allows obje...read more

Data structures are ways of organizing and storing data in a computer so that it can be accessed and used efficiently.

• Data structures define the way data is stored, accessed, and manipulated in a computer program.

• Examples include arrays, linked lists, stacks, queues, trees, and graphs.

The 4 pillars of OOPs are Abstraction, Encapsulation, Inheritance, and Polymorphism.

• Abstraction: Hiding implementation details and showing only necessary information.

• Encapsulation: Binding data and functions together to protect data from outside interference.

• Inheritance: Creating new classes from existing ones, inheriting properties and methods.

• Polymorphism: Ability of objects to take on multiple forms or behaviors.

A Binary Search Tree (BST) is a data structure where each node has at most two children, with the left child being less than the parent and the right child being greater.

• Nodes in a BST are arranged in a hierarchical order where each node has a left child and a right child.

• The left child of a node contains a value less than the parent node, while the right child contains a value greater than the parent node.

• BST allows for efficient searching, insertion, and deletion operations...read more
