Serialization is the process of converting complex data structures into a format that can be stored or transmitted.
Python provides several modules for serialization such as pickle, json, and msgpack.
Pickle is used for serializing and de-serializing Python objects.
JSON is used for serializing and de-serializing data in a human-readable format.
Msgpack is used for serializing and de-serializing data in a compact binary fo...
Joins in SQL are used to combine data from two or more tables based on a related column.
Types of joins include inner join, left join, right join, and full outer join.
Inner join returns only the matching rows from both tables.
Left join returns all the rows from the left table and matching rows from the right table.
Right join returns all the rows from the right table and matching rows from the left table.
Full outer join ...
API authentication using tokens
Tokens are unique strings generated by the server and sent to the client upon successful login
The client then sends the token with each subsequent request to the server
The server verifies the token and grants access to the requested resource if the token is valid
Tokens can have an expiration time to ensure security
Common token-based authentication methods include JWT and OAuth

Check if binary tree is balanced or not.
A balanced binary tree has the height of left and right subtrees differ by at most 1.
Recursively check the height of left and right subtrees and compare.
Use a helper function to calculate the height of a subtree.
Time complexity: O(nlogn) for a balanced tree, O(n^2) for a skewed tree.
Detect loops in a linked list.
Use two pointers, one moving at a faster pace than the other.
If there is a loop, the faster pointer will eventually catch up to the slower one.
To detect the start of the loop, reset one pointer to the head and move both pointers at the same pace.

Given a railway seat number, determine if it is valid and identify its berth type.
Parse input integer 't' for number of test cases
For each test case, check if seat number is valid (1 <= N <= 100)
Identify berth type based on seat number and output the result
Possible berth types are Lower, Middle, Upper, Side Lower, and Side Upper

First they asked me to introduce myself then they started questioning on oops concept from basic to advance level such as inheritance, polymorphism, abstraction, exception handling , STL etc. Next they started questioning on data structures. They asked me the logic of “how to find the middle of a linked list”.
You are provided with a square matrix. Your task is to return true
if the matrix is symmetric; otherwise, return false
.
A symmetric matrix is characterized by its transpose being eq...
Check if a square matrix is symmetric by comparing it with its transpose.
Iterate through the matrix and compare each element with its corresponding element in the transpose
If any pair of elements do not match, return false immediately
If all pairs match, return true at the end
Tip 1 : Clear the basic concepts of data structure and OOPs.
Tip 2 : Use coding ninja platform and Hackerearth for practice on coding skills.
