10+ Interview Questions and Answers

Check if a tree is balanced by comparing the heights of its left and right subtrees.

• Calculate the height of the left subtree and the height of the right subtree.

• If the difference between the heights is greater than 1, the tree is not balanced.

• Recursively check if both the left and right subtrees are balanced.

• If both subtrees are balanced and the height difference is less than or equal to 1, the tree is balanced.

Pattern matching in large corpus using NLP

• Use natural language processing techniques to identify patterns in a large corpus

• Apply techniques like tokenization, part-of-speech tagging, and named entity recognition

• Utilize regular expressions or rule-based matching to identify specific patterns

• Consider using machine learning algorithms like sequence labeling or clustering

• Examples: finding email addresses, detecting dates, identifying named entities

Attributes of a fan include size, speed, power source, noise level, and direction of rotation.

• Size (e.g. diameter of blades)

• Speed (e.g. rotations per minute)

• Power source (e.g. electric, battery)

• Noise level (e.g. decibels)

• Direction of rotation (e.g. clockwise, counterclockwise)

Designing a library management system to efficiently organize and track library resources.

• Utilize a database to store information on books, patrons, and transactions

• Implement a user-friendly interface for librarians to add, edit, and delete records

• Incorporate features such as search functionality, book reservations, and overdue notifications

There are several algorithms used for classification, including decision trees, logistic regression, k-nearest neighbors, and support vector machines.

• Decision trees: a tree-like model where each internal node represents a test on an attribute, each branch represents the outcome of the test, and each leaf node represents a class label

• Logistic regression: a statistical method that uses a logistic function to model a binary dependent variable

• K-nearest neighbors: a non-parametric...read more

OOPs stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.

• OOPs focuses on creating objects that contain data and methods to manipulate that data.

• Encapsulation, inheritance, and polymorphism are key principles of OOPs.

• Examples of OOP languages include Java, C++, and Python.

DMA stands for Direct Memory Access, a feature that allows hardware devices to transfer data to/from memory without involving the CPU.

• DMA is used to offload data transfer tasks from the CPU, improving overall system performance.

• Context switching is the process of saving and restoring the state of a CPU so that multiple processes can share the same CPU.

• DMA and context switching are both important concepts in embedded systems design.

• Example: In a system with a network interface...read more

Pipeline in ARM is a technique used to increase the performance of the processor by overlapping the execution of multiple instructions.

• Pipeline allows multiple instructions to be processed simultaneously in different stages of execution.

• It helps in reducing the overall execution time of a program.

• ARM processors typically have a 3-stage pipeline, but some newer designs have more stages for better performance.

• Example: In a 3-stage pipeline, the fetch, decode, and execute stages...read more
