- Ans.
CORS allows web applications to make requests to a different domain than the one it originated from.
CORS is enabled on the server side by setting the 'Access-Control-Allow-Origin' header to specify which domains are allowed to make requests.
Options requests are sent by the browser to check if the server allows the actual request. The server should respond with the appropriate headers.
CORS can be configured to allow spe...

- 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.

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

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.
