- Q2. Difference between element and elements
- Ans.
Element is a singular object, while elements refer to multiple objects.
Element is a single item in a collection or array.
Elements are multiple items in a collection or array.
Example: 'apple' is an element in the array ['apple', 'banana', 'orange'].
Example: 'banana' and 'orange' are elements in the same array.
- Q3. What is Bva in testing
- Ans.
Boundary Value Analysis (BVA) is a testing technique used to identify errors at boundaries of input ranges.
BVA involves testing at the boundaries of valid and invalid input ranges
It helps in identifying errors that occur at the edges of input values
Examples include testing a login form with minimum and maximum character limits for password
BVA is used to ensure that the software behaves correctly at the boundaries of in
- Q4. What is acid property in sql
- Ans.
ACID properties in SQL refer to a set of properties that ensure database transactions are processed reliably.
ACID stands for Atomicity, Consistency, Isolation, and Durability
Atomicity ensures that either all operations in a transaction are completed successfully or none are
Consistency ensures that the database remains in a consistent state before and after the transaction
Isolation ensures that multiple transactions can...
- Q5. What is difference between schema and database testing
- Ans.
Schema testing focuses on the structure of the database, while database testing focuses on the data within the database.
Schema testing ensures that the database tables, columns, relationships, and constraints are correctly defined.

- Q2. What is the Time Complexity of Binary Search and it's derivation
- Ans.
Binary Search has a time complexity of O(log n) and is derived from dividing the search space in half at each step.
Binary Search is a search algorithm that works on sorted arrays.
It starts by comparing the target value to the middle element of the array.
If the target value is smaller, the search continues on the lower half of the array.
If the target value is larger, the search continues on the upper half of the array.

- Q3. Write code for QuickSort
- Ans.
QuickSort is a sorting algorithm that uses divide and conquer approach.
Choose a pivot element from the array
Partition the array into two sub-arrays, one with elements less than the pivot and one with elements greater than the pivot
Recursively apply the above steps to the sub-arrays
Combine the sorted sub-arrays to get the final sorted array
- Q4. Write code for Fibonacci Series using Recursion, Iteration and Dynamic Programming
- Ans.
Code for Fibonacci Series using Recursion, Iteration and Dynamic Programming
Recursion: Define a function that calls itself with the previous two numbers in the series as arguments
Iteration: Use a loop to calculate the series by adding the previous two numbers in each iteration
Dynamic Programming: Store the previous two numbers in variables and use them to calculate the next number in the series
- Q5. How to implement an operation with Stacks which will be similar to Queue
- Ans.
Implementing a Queue using Stacks
Use two stacks to implement a queue
Push elements onto the first stack
When dequeuing, pop all elements from the first stack and push onto the second stack
Pop the top element from the second stack to dequeue
If the second stack is empty, pop all elements from the first stack and push onto the second stack
- Q6. Write code for MergeSort
- Ans.
MergeSort is a divide and conquer algorithm that sorts an array of strings.

- Q9. How the letters of a text are determined(Basically about OCR)
- Q10. Write code for Insertion Sort and Selection Sort and find their time complexities and also the cases where their usage is efficient
- Q11. Explain about Counting Sort
- Ans.
Counting Sort is a sorting algorithm that sorts elements by counting the number of occurrences of each unique element.
Count the occurrences of each element in the array
Calculate the cumulative sum of the counts
Place each element in the sorted array based on its count and cumulative sum
Time complexity is O(n+k) where n is the number of elements and k is the range of input
Example: Sort an array of strings based on their
- Q12. When we type a part of a word in chrome, how is it able to show all the types of words, which are consisted of that part
- Ans.
Chrome uses an algorithm to predict and suggest words based on user input.
Chrome's algorithm uses a combination of user history, bookmarks, and popular searches to predict and suggest words.
The algorithm also takes into account the frequency and recency of the user's input.
Chrome's suggestion feature is powered by Google's Autocomplete API, which uses machine learning to predict and suggest words.

Interview Preparation Tips
Experience: First Question, at the start I was not able to answer and he gave me an hint(He asked me the insertion in an array). So, I got the idea for the insertion in Linked List and was able to answer it.
Remaining questions, I was able to answer confidently.
Tips: Take your own time in answering a question and be clear over your answer before telling about the code that you have written.
If you don't know an answer for some question, just keep telling him simple cases(which are valid), so that the interviewer will sometimes try to guide you through the solution.
Round: Technical Interview
Experience: I was able to answer all the questions confidently, since I know the answers for them, But the last question was out of my scope and I explained based on my intuition and knowledge.
