To find the 3rd largest element in an array, we can sort the array and select the appropriate index.
Sort the array in descending order and select the element at index 2.
Example: For array [5, 3, 8, 1, 2], sorted array is [8, 5, 3, 2, 1]. 3rd largest is 3.
Alternatively, use a set to remove duplicates and then sort.
Example: For array [5, 5, 3, 8, 1], unique sorted array is [8, 5, 3, 1]. 3rd largest is 3.
Find the second largest number in an array of integers using Java.
1. Sort the array in descending order and pick the second element. Example: [3, 1, 4, 2] -> sorted: [4, 3, 2, 1] -> second largest: 3.
2. Use a loop to track the largest and second largest numbers. Example: for array [5, 3, 9, 1], largest=9, secondLargest=5.
3. Handle duplicates by checking if the current number is greater than the largest and n...
Postman allows users to create collection and environment variables for efficient API testing.
To create a collection variable, go to the collection, click on 'Variables', and add key-value pairs.
Example: Add a variable 'authToken' with value '12345' for authentication in requests.
To create an environment variable, click on the 'Environment' dropdown, select 'Manage Environments', and add a new environment.
Example:...
TestNG is a testing framework inspired by JUnit, designed for test configuration and parallel execution.
Supports annotations like @Test, @BeforeMethod, @AfterMethod.
Allows grouping of tests using @Test(groups = {"group1"}).
Data Providers can be defined using @DataProvider annotation.
Example of Data Provider: @DataProvider(name = "data") public Object[][] dataMethod() { return new Object[][] { {1, 2}, {3, 4} }; }

Newman reports in Postman can be generated using the command line tool Newman to run collections and export results.
Install Newman globally using npm: `npm install -g newman`.
Run your Postman collection with Newman: `newman run <collection-file.json>`.
To generate an HTML report, use: `newman run <collection-file.json> -r html`. This creates an HTML report.
You can specify the output file for the report:...
UI focuses on the visual aspects of a design, while UX focuses on the overall user experience.
UI (User Interface) deals with the look and feel of a design, including colors, typography, and layout.
UX (User Experience) focuses on the overall experience of the user, including ease of use, accessibility, and efficiency.
UI is more about the visual elements, while UX is about the functionality and usability of a design...
UX laws are principles and guidelines that help designers create user-friendly and intuitive experiences.
Hick's Law - The time it takes to make a decision increases with the number of choices available.
Fitts's Law - The time to move to a target is a function of the distance to the target and the size of the target.
Law of Proximity - Objects that are near each other are perceived as a group.
Law of Similarity - Obje...
Fitts's Law predicts the time required to rapidly move to a target area, based on size and distance.
Fitts's Law formula: MT = a + b * log2(D/W), where MT is movement time, D is distance, and W is width of the target.
Larger targets are easier to hit, reducing movement time; for example, a big button is quicker to click than a small one.
Targets closer to the user are faster to reach; for instance, a menu item at the...
Test cases for an air conditioner (AC) to ensure functionality and performance under various conditions.
Verify power on/off functionality: Ensure the AC turns on and off with the remote and manual switch.
Check temperature settings: Test if the AC can be set to different temperatures (e.g., 16°C, 24°C, 30°C) and maintains them.
Test cooling efficiency: Measure the temperature drop in a room after a set period (e.g.,...

- Q2. What is variable & Rules? Loops & Type of Loops ? OOPs Concept
- Ans.
Variables are containers for storing data. Loops are used to iterate over a sequence of elements. OOPs is a programming paradigm based on objects and classes.
Variables are used to store data in memory. They can be assigned different values and data types.
Rules for naming variables: must start with a letter or underscore, can contain letters, numbers, and underscores, cannot start with a number.
Loops are used to execute...

I appeared for an interview in Jan 2025.
I attended a walk-in interview on January 31, 2025. There was only one round, where the interviewer asked me several theoretical concepts related to JavaScript, including var, let, const, closures, promises, map, filter, reduce, and hoisting. He then asked me a few questions about React JS, such as "What is React?" and "What are hooks?" He also requested that I write the syntax for the useEffect hook. After that, he assigned me some coding tasks, which included finding the sum of an array, identifying the second largest number from array, filtering out the odd numbers from an array, and providing an example of the reduce method and filter method

- Q1. Regression testing vs re-testing
- Ans.
Regression testing is testing the entire application after changes, while re-testing is testing specific areas that were previously found to have issues.
Regression testing involves testing the entire application to ensure that new changes have not affected existing functionality.
Re-testing focuses on testing specific areas that were previously found to have issues to ensure they have been fixed.
Regression testing is ty...

I appeared for an interview in May 2025, where I was asked the following questions.
- Q1. Basic python question
- Q2. Find 3rd largest element
- Ans.
To find the 3rd largest element in an array, we can sort the array and select the appropriate index.
Sort the array in descending order and select the element at index 2.
Example: For array [5, 3, 8, 1, 2], sorted array is [8, 5, 3, 2, 1]. 3rd largest is 3.
Alternatively, use a set to remove duplicates and then sort.
Example: For array [5, 5, 3, 8, 1], unique sorted array is [8, 5, 3, 1]. 3rd largest is 3.
