My final year project was on developing a web-based inventory management system using Java and MySQL.

• Developed using Java and MySQL

• Web-based inventory management system

• Implemented basic OOPs concepts

• Used MVC architecture for better code organization

• Included features like user authentication, product management, and order tracking

AEM architecture is based on OSGi framework and follows a modular approach.

• AEM uses Apache Sling framework for request processing and resource resolution.

• It has a content repository based on Apache Jackrabbit Oak.

• AEM also has a dispatcher module for caching and load balancing.

• It follows a component-based architecture where each component is a self-contained module.

• AEM also supports customization through templates, work

A flip-flop is a digital circuit that can store one bit of information. It has two stable states and is used for memory storage and data transfer.

• Flip-flops are made up of logic gates, such as NAND or NOR gates.

• They have two stable states: SET and RESET.

• The SET state is when the output is high and the RESET state is when the output is low.

• Flip-flops can be edge-triggered or level-triggered.

• Examples of flip-flops includ

IaaS, PaaS and SaaS are cloud computing models that differ in the level of control and responsibility of the user.

• IaaS (Infrastructure as a Service) provides virtualized computing resources like servers, storage, and networking. Examples include Amazon Web Services (AWS) and Microsoft Azure.

• PaaS (Platform as a Service) provides a platform for developing, testing, and deploying applications. Examples include Google App ...read more

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 ...read more

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)
