Longest common subsequence is the longest sequence of characters that appear in the same order in both strings.
Use dynamic programming to solve this problem efficiently.
Create a 2D array to store the lengths of longest common subsequences.
Iterate through the strings and fill the array based on the characters' matches.
Trace back the array to find the actual longest common subsequence.

You are given two rectangles situated on a 2-D coordinate plane, which may overlap. Your task is to compute the total area covered by these rectangles.
Calculate total area covered by two overlapping rectangles on a 2-D plane.
Calculate the area of each rectangle separately using the given coordinates.
Find the overlapping region by determining the intersection of the two rectangles.

Add the areas of the two rectangles and subtract the area of the overlapping region to get the total area cov
Given an array ARR
consisting of N
integers, rearrange the elements such that all negative numbers are located before all positive numbers. The orde...
Yes, this can be achieved by using a two-pointer approach to rearrange the array with negative numbers at the beginning.
Use two pointers, one starting from the beginning and one from the end of the array.
Swap elements at the two pointers if one is negative and the other is positive, and move the pointers accordingly.
Continue this process until the two pointers meet in the middle of the array.
The resulting array will ha...

Return the middle node of a singly linked list, considering odd and even number of nodes.
Traverse the linked list with two pointers, one moving at twice the speed of the other
When the faster pointer reaches the end, the slower pointer will be at the middle node
Handle cases for odd and even number of nodes separately
Return null if the list is empty
Given a positive integer N
, your task is to return all the prime numbers less than or equal to N
.
1) A prime number is a number that has only two factors:...
Return all prime numbers less than or equal to a given positive integer N.
Iterate from 2 to N and check if each number is prime using a helper function.
A number is prime if it is not divisible by any number from 2 to its square root.
Store and return the prime numbers in an array in increasing order.

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
Use a script to iterate through each HTML page, locate phone numbers, and update their format.
Write a script using a programming language like Python or JavaScript to iterate through each HTML page
Use regular expressions to locate phone numbers in the pages
Update the format of the phone numbers as needed (e.g. adding country code, changing separators)
Save the updated HTML pages with the new phone number format
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
