Different types of regression analysis include linear regression, logistic regression, polynomial regression, ridge regression, and lasso regression.
Linear regression: Predicts a continuous outcome based on one or more input features.
Logistic regression: Predicts the probability of a binary outcome.
Polynomial regression: Fits a curve to the data by including polynomial terms.
Ridge regression: Adds a penalty term to the...
Confusion matrix is a table used to evaluate the performance of a classification model.
It is a matrix with rows representing the actual class and columns representing the predicted class.
It helps in visualizing the performance of a classification model by showing the counts of true positive, true negative, false positive, and false negative predictions.
It is commonly used in machine learning to assess the quality of th...
Transformer based models use self-attention mechanism to capture long-range dependencies in data.
Transformer models consist of encoder and decoder layers.
Self-attention mechanism allows each word to attend to all other words in the input sequence.
Positional encoding is added to input embeddings to provide information about the position of words.
Transformer models have achieved state-of-the-art results in various NLP ta...
Various NLP techniques for text extraction include Named Entity Recognition, Part-of-Speech tagging, and Dependency Parsing.
Named Entity Recognition (NER) identifies entities such as names, dates, and locations in text.
Part-of-Speech tagging assigns grammatical categories to words in a sentence.
Dependency Parsing analyzes the grammatical structure of a sentence to identify relationships between words.

Given a railway seat number, determine if it is valid and identify its berth type.
Parse input integer 't' for number of test cases
For each test case, check if seat number is valid (1 <= N <= 100)
Identify berth type based on seat number and output the result
Possible berth types are Lower, Middle, Upper, Side Lower, and Side Upper
Round duration - 90 mins
Round difficulty - Hard
First they asked me to introduce myself then they started questioning on oops concept from basic to advance level such as inheritance, polymorphism, abstraction, exception handling , STL etc. Next they started questioning on data structures. They asked me the logic of “how to find the middle of a linked list”.
You are provided with a square matrix. Your task is to return true
if the matrix is symmetric; otherwise, return false
.
A symmetric matrix is characterized by its transpose being eq...
Check if a square matrix is symmetric by comparing it with its transpose.
Iterate through the matrix and compare each element with its corresponding element in the transpose
If any pair of elements do not match, return false immediately
If all pairs match, return true at the end
Tip 1 : Clear the basic concepts of data structure and OOPs.
Tip 2 : Use coding ninja platform and Hackerearth for practice on coding skills.
Tip 3 : Use Geeks For Geeks for interview preparation.
Tip 1: Make your resume short and try to make it of one page only.
Tip 2: Add relevant keywords

Check if binary tree is balanced or not.
A balanced binary tree has the height of left and right subtrees differ by at most 1.
Recursively check the height of left and right subtrees and compare.
Use a helper function to calculate the height of a subtree.
Time complexity: O(nlogn) for a balanced tree, O(n^2) for a skewed tree.
Detect loops in a linked list.
Use two pointers, one moving at a faster pace than the other.
If there is a loop, the faster pointer will eventually catch up to the slower one.
To detect the start of the loop, reset one pointer to the head and move both pointers at the same pace.

API testing methods involve functional, performance, security, and exploratory testing.
Functional testing ensures that the API meets the requirements and specifications.
Performance testing checks the API's response time, throughput, and resource utilization.
Security testing verifies the API's authentication, authorization, and encryption mechanisms.
Exploratory testing involves ad-hoc testing to discover defects and usa...
Sanity and Smoke are types of software testing. Sanity tests a specific functionality while Smoke tests the entire system.
Sanity testing is a narrow and deep testing approach while Smoke testing is a broad and shallow testing approach.
Sanity testing is performed after a small change in code while Smoke testing is performed after a major change in code.
Sanity testing is used to check if the critical functionalities are ...
Retesting is testing the same functionality again after fixing the defects. Regression is testing the unchanged functionality after making changes.
Retesting is done to ensure that the defects have been fixed and the functionality is working as expected.
Regression is done to ensure that the changes made to the software have not affected the existing functionality.
Retesting is a subset of regression testing.
Retesting is ...
