Hello Coding Lover,
Just Learn this Amazing technique which is discussed in this tutorial and you will be able to solve more than 10 questions on leetcode.

In this video, I have explained two pointer technique which is the optimal way to solve problems related to arrays, strings and linked list in O(N) time.

There are a lot of coding interview problems which can be solved by using this technique in an optimized way.

Hello Coding Lover,
In this video, I have explained a general approach to solve climbing staircase problem which is based on fibonacci pattern.

how to identify the pattern and apply the same to solve such DP problems.

Here I have explained, four different ways to solve this problem.

Recursive Solution
Top-down with memoization
Bottom-up
Efficient solution

How many of you thought that I have solved the problem in an interview but still did not 𝗴𝗲𝘁 𝘁𝗵𝗲 𝗼𝗳𝗳𝗲𝗿 or did not get what I expected?

If this has happened to you then this tutorial will be going to an eye-opener for you.

Generally, the candidate solves the problem with a brute force approach but ignore the optimize solution.
If you know this technique you can 𝗱𝗿𝗮𝘀𝘁𝗶𝗰𝗮𝗹𝗹𝘆 𝗿𝗲𝗱𝘂𝗰𝗲 𝘁𝗵𝗲 𝘁𝗶𝗺𝗲 𝗰𝗼𝗺𝗽𝗹𝗲𝘅𝗶𝘁𝘆 𝗼𝗳 𝘆𝗼𝘂𝗿 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 𝗳𝗿𝗼𝗺 𝗢(𝗻²) 𝘁𝗼 𝗢(𝗻) and you can get a slight advantage in your interview.


And this technique is known as 𝗦𝗹𝗶𝗱𝗶𝗻𝗴 𝗪𝗶𝗻𝗱𝗼𝘄 𝗧𝗲𝗰𝗵𝗻𝗶𝗾𝘂𝗲 which is useful for solving problems related to 𝗮𝗿𝗿𝗮𝘆𝘀 𝗼𝗿 𝘀𝘁𝗿𝗶𝗻𝗴𝘀.

Hello Coding Lover,

In this video tutorial, I have explained the beautiful problem-solving technique called 𝗥𝗲𝗰𝘂𝗿𝘀𝗶𝗼𝗻 and its applications.

If you can visualize this 2D image in 3D then probably you would have heard of 𝗥𝗲𝗰𝘂𝗿𝘀𝗶𝗼𝗻.

Hi Coding Lover,

Here is one more tutorial which will 𝗲𝗻𝗵𝗮𝗻𝗰𝗲 𝘆𝗼𝘂𝗿 𝗱𝗲𝗯𝘂𝗴𝗴𝗶𝗻𝗴 𝘀𝗸𝗶𝗹𝗹𝘀.

Today, I have explained how to 𝘃𝗶𝘀𝘂𝗮𝗹𝗶𝘇𝗲 𝘆𝗼𝘂𝗿 𝗰𝗼𝗱𝗲 𝗲𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 𝗳𝗹𝗼𝘄 and get help from others if you stuck.

It supports most of the language like 𝗖, 𝗖++, 𝗝𝗮𝘃𝗮, 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁, 𝗧𝘆𝗽𝗲𝗦𝗰𝗿𝗶𝗽𝘁, 𝗥𝘂𝗯𝘆 etc.
