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
