The manifest.json file contains the most important information of a Chrome extension.
The manifest.json file includes the version number, permissions, content scripts, background scripts, and other important details.
It is located in the root directory of the extension.
It is required for all Chrome extensions.
Example: "manifest_version": 2, "version": "1.0", "permissions": ["tabs", "storage"]
Hashtable is faster for finding an item than a sorted list.
Hashtable has constant time complexity O(1) for finding an item.
Sorted list has logarithmic time complexity O(log n) for finding an item.
Hashtable uses hashing to directly access the item's location.
Sorted list requires binary search to find the item's location.
Hashtable is ideal for large datasets with frequent lookups.
Sorted list is ideal for datasets that re
JSON and XML are the most popular data interchange formats when using APIs.
JSON (JavaScript Object Notation) is a lightweight format that is easy to read and write. It is widely used in web APIs.
XML (Extensible Markup Language) is a more complex format that is also widely used in web APIs.
Other formats include CSV (Comma Separated Values), YAML (YAML Ain't Markup Language), and Protocol Buffers.
Popular APIs for Social Commerce services
Facebook Graph API for social media integration
Instagram API for photo sharing and tagging
Twitter API for real-time updates and customer engagement
Pinterest API for product discovery and sharing
Google Maps API for location-based services
PayPal API for secure payment processing

I would start by analyzing user search patterns and frequently searched keywords
Then, I would create a database of these keywords and their associated search results
I would use indexing services to quickly retrieve relevant results for each keyword
I would also implement machine learning algorithms to improve the accuracy of suggestions over time
Check if a number is a power of 2 and odd.
To check if a number is a power of 2, use bitwise AND operator with the number and its predecessor. If the result is 0, it is a power of 2.
To check if a number is odd, use modulus operator with 2. If the result is 1, it is odd.
Example code in Python:
def is_power_of_two(num):
return num & (num - 1) == 0
def is_odd(num):
return num % 2 == 1

An array can be used to store the nodes in the required order.
A linked list can be used ...

This was a typical DS/Algo where I was asked to solve two questions related to Binary Trees and write the pseudo code for both of them followed by some theoretical questions related to Operating Systems.
Given a binary search tree (BST) consisting of integers and containing 'N' nodes, your task is to find and return the K-th largest element in this BST.
If there is no K-th la...
Find the K-th largest element in a BST.
Perform reverse in-order traversal of the BST to find the K-th largest element.
Keep track of the count of visited nodes to determine the K-th largest element.
Return -1 if there is no K-th largest element in the BST.
Determine if the given binary tree is height-balanced. A tree is considered height-balanced when:
Determine if a given binary tree is height-balanced by checking if left and right subtrees are balanced and their height difference is at most 1.
Check if the left subtree is balanced
Check if the right subtree is balanced
Calculate the height difference between the left and right subtrees
Return 'True' if all conditions are met, otherwise return 'False'
Zombie process is a terminated process that has completed execution but still has an entry in the process table. Orphan process is a process whose parent process has terminated.
Zombie process is created when a child process completes execution but its parent process has not yet read its exit status.
Zombie processes consume system resources and should be cleaned up by the parent process using wait() system call.

I found the online coding round of Flipkart to be quite difficult based on the constraints of the problem and their time limits. I coded the first problem quite easily but on the second and the third problem , my code could only pass a few test cases and gave TLE for most of them. Both the questions required very efficient solution and the last 5 to 10 Test Cases carried more weight than the rest so I didn't get through this round.
