Last time I wrote article about the KMP algorithm which is a pattern matching algorithm, so today I will explain one more pattern matching algorithm which is Z-Algorithm. This algorithm will take O(n) time complexity and the main place where we can use this algorithm where we need to find…

In my last story I wrote about blockchain and while learning about blockchain and ethereum technology i also learnt how to make a dApp using ReactJs , solidity language, Truffle and many more technology. So in this and next article i will try to explain everything from technology to code…

Clean code is one of the famous book, written for programmers. It is an old book but still has a lot of useful information for current programmers. So I will share some of the top tips given in this famous book. …

Blockchain is becoming popular day by day and many of you heard it from your friend or watch a lot of videos about it. But in this article, I will focus on why should need to know about blockchain technology. Blockchain is a Disruptive Technology Disruptive technology is the technology that affects the normal operation…

Hello Everyone Today I will explain one of the standard pattern matching algorithms named as KMP(Knuth-Morris-Pratt) Algorithm. It will reduce the time complexity for pattern matching. So let us first see the Naive approach and understand the problem with the approach.

Hi Everyone, Today I am going to explain one standard problem in which you have to check a cycle in a directed graph using DFS. First, let us understand what we need to do about this problem. Firstly, we need to understand type of edges. There are 4 types of…

This question is quite easy if we use recursion. But how do we know that we need to use recursion? Basically, this type of question is asking for all possible solutions. we only have a number that represents pair of parenthesis. …
