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...

A thief is planning to rob a store and can carry a maximum weight of 'W' in his knapsack. The store contains 'N' items where the ith item has a weight of 'wi' and a value of...
Yes, the 0/1 Knapsack problem can be solved using dynamic programming with a space complexity of not more than O(W).
Use a 1D array to store the maximum value that can be stolen for each weight capacity from 0 to W.
Iterate through each item and update the array based on whether including the item would increase the total value.
The final value in the array at index W will be the maximum value that can be stolen.
Given an array or list of integers 'ARR', identify the second largest element in 'ARR'.
If a second largest element does not exist, return -1.
ARR = [2,...
Find the second largest element in an array of integers.
Iterate through the array to find the largest and second largest elements.
Handle cases where all elements are identical.
Return -1 if a second largest element does not exist.

To scale a system, consider horizontal and vertical scaling, load balancing, caching, database sharding, and microservices architecture.
Implement horizontal scaling by adding more instances of the application to distribute the load.
Consider vertical scaling by upgrading the hardware resources of the existing server.
Use load balancing to evenly distribute incoming network traffic across multiple servers.
Implement cachin...
