A mutable type is a data type whose values can be changed after they are created.
Mutable types include lists, dictionaries, and sets in Python.
Changes to mutable objects affect all references to that object.
Example: list1 = [1, 2, 3], list1[0] = 4 will change the value of list1 to [4, 2, 3].
A functional interface is an interface that contains only one abstract method.
Functional interfaces can have multiple default or static methods.
Examples include Runnable, Callable, and ActionListener interfaces.
Functional interfaces can be implemented using lambda expressions.
Java 17 introduces new features like sealed classes, pattern matching for switch statements, and more.
Sealed classes restrict which classes can be subclasses
Pattern matching for switch statements simplifies code by combining declaration and assignment

AI stands for Artificial Intelligence, which is the simulation of human intelligence processes by machines, especially computer systems.
AI involves the development of algorithms that can perform tasks that typically require human intelligence.
Examples of AI include speech recognition, image recognition, natural language processing, and autonomous vehicles.
AI can be categorized into narrow AI (focused on a specific task...
Machine learning is a branch of artificial intelligence that involves developing algorithms and models that can learn from and make predictions or decisions based on data.
Machine learning uses algorithms to analyze data, learn from it, and make predictions or decisions.
It is used in various fields such as healthcare, finance, marketing, and more.
Examples of machine learning applications include recommendation systems, ...

Merge Sort is a divide and conquer algorithm that sorts an array by dividing it into two halves, sorting them separately, and then merging the sorted halves.
Divide the array into two halves
Recursively sort the two halves
Merge the sorted halves
Find pairs of integers in a BST whose sum is equal to a given number.
Traverse the BST and store the values in a hash set.
For each node, check if (X - node.value) exists in the hash set.
If yes, add the pair (node.value, X - node.value) to the result.
Continue traversal until all nodes are processed.
Merge overlapping time intervals into mutually exclusive intervals.
Sort the intervals based on their start time.
Iterate through the intervals and merge overlapping intervals.
Output the mutually exclusive intervals.
Example: [(1,3), (2,6), (8,10), (15,18)] -> [(1,6), (8,10), (15,18)]
Different types of hashing and alternative for Linear Chaining
Different types of hashing include division, multiplication, and universal hashing
Alternative for Linear Chaining is Open Addressing
Open Addressing includes Linear Probing, Quadratic Probing, and Double Hashing
An AVL tree is a self-balancing binary search tree where the heights of the left and right subtrees differ by at most one.
AVL tree is a binary search tree with additional balance factor for each node.
The balance factor is the difference between the heights of the left and right subtrees.
Insertion and deletion operations in AVL tree maintain the balance factor to ensure the tree remains balanced.
Rotations are performed ...
Find the minimum number of squares whose sum equals to a given number n.
Use dynamic programming to solve the problem efficiently.
Start with finding the square root of n and check if it is a perfect square.
If not, then try to find the minimum number of squares required for the remaining number.
Repeat the process until the remaining number becomes 0.
Return the minimum number of squares required for the given number n.
Insertion sort for a singly linked list.
Traverse the list and compare each node with the previous nodes
If the current node is smaller, swap it with the previous node
Repeat until the end of the list is reached
Time complexity is O(n^2)
