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

This tutorial ranked number 1 on Google and YouTube.so thought of sharing with you all.

If you are a competitive programmer or preparing for competitive programming or solve coding problems online then you would have come across one algorithm called prefix sum.
But most of people do know the benefit of this algorithm.

Here is the tutorial which explains why you must know prefix-sum algorithm.
