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

Designing Google Suggest system
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

Multiple data structures are used to print nodes in a specific order. One data structure cannot be used alone.
The given order suggests a depth-first search traversal of a tree-like structure.
A stack can be used to keep track of the nodes to be visited.
A queue can be used to store the children of a node in the order they are visited.
An array can be used to store the nodes in the required order.
A linked list can be used ...
Find largest pen using minimum comparisons with tops.
Divide pens into two groups and compare largest pen from each group with largest top.
Repeat the process with the group containing the largest pen until only one pen is left.
The remaining pen is the largest pen.
Total number of comparisons required is 2n-3.
Given n dice with 'a' sides and sum b, return no. of ways to obtain b. Optimize time and space complexity.
Use dynamic programming to reduce time complexity
Create a 2D array to store the number of ways to obtain each sum for each number of dice
Use rolling arrays to optimize space complexity
Example: n=2, a=6, b=7 -> 6 ways to obtain sum 7
Example: n=3, a=4, b=8 -> 21 ways to obtain sum 8
Sort 128 GB data on 2 machines with 64 GB RAM each. Extend to 1000 machines.
