LINQ joins on 2 tables allow for combining data from both tables based on a common key.
Use the 'join' keyword in LINQ to join two tables based on a common key
Specify the key to join on using 'equals' keyword
Select the desired columns from both tables in the result
Open close principle states that a class should be open for extension but closed for modification.
Classes should be open for extension through inheritance or implementing interfaces
Classes should be closed for modification to avoid breaking existing code
Example: Using abstract classes or interfaces to define behavior and allowing subclasses to implement specific functionality

Diameter of a binary tree is the longest path between any two leaf nodes.
Calculate the height of left and right subtrees recursively.
Calculate the diameter recursively using the formula max(left_height + right_height + 1, max(left_diameter, right_diameter)).
Return the maximum diameter.
To find interchanged terms from an AP series
Identify the common difference between terms
Swap the positions of adjacent terms
Check if the new series is also an AP
Repeat until no more interchanged terms can be found
Database indexing is a technique to improve the performance of database queries.
Indexing creates a data structure that allows for faster retrieval of data.
Indexes are created on one or more columns of a table.
Queries that use indexed columns can be executed faster.
Indexes can be clustered or non-clustered.
Clustered indexes determine the physical order of data in a table.
Non-clustered indexes create a separate structure...

DHCP assigns IP addresses to devices on a network
DNS translates domain names to IP addresses
DHCP reduces the need for manual IP address configuration
DNS allows users to access websites using domain names instead of IP addresses

Design a stack that supports getmin in O(1) time and O(1) space complexities.
Use two stacks, one for storing the actual values and the other for storing the minimum values.
When pushing a new value, check if it is smaller than the current minimum value and push it to the minimum stack if it is.
When popping a value, check if it is the current minimum value and pop it from the minimum stack if it is.
To get the minimum val...
Binary tree traversal is the process of visiting each node in a binary tree exactly once in a specific order.
There are three main types of binary tree traversal: inorder, preorder, and postorder.
Inorder traversal visits the left subtree, then the root, then the right subtree.
Preorder traversal visits the root, then the left subtree, then the right subtree.
Postorder traversal visits the left subtree, then the right subt...
LRU cache is a data structure that stores the most recently used items and discards the least recently used items.
LRU stands for Least Recently Used
It has a fixed size and when the cache is full, the least recently used item is removed to make space for a new item
It uses a combination of a doubly linked list and a hash map to achieve O(1) time complexity for both insertion and deletion
Example: A web browser cache that ...
