Find Loop in a Linked List

Image
 Problem Statement In this problem, we are given a linked list with a loop. We have to find the first node of the loop in the linked list. Problem Statement Understanding Let’s try to understand the problem statement with the help of examples. Suppose the given list is: According to the problem statement, we need to find the starting node of the loop. From the linked list, we can see that there is a loop in the linked list starting at node with value 3 and containing 3 nodes 3, 5, and 7. The last node of the loop points back to the first node of the loop. As node with value 3 is the first node of the loop, so we will return 3 as output. Approach and Algorithm (Floyd’s Cycle Detection) Our approach will be simple: 1) Firstly, we have to detect the loop in the given linked list. For detecting a loop in any linked list, we know the most efficient algorithm is the  Floyd Cycle detection Algorithm . 2) In Floyd's cycle detection algorithm, we initialize 2 pointers,  slow ...

GIT Rebase vs Merge

Image
  How does Git Work? For understanding the working of git, we need to understand the two fundamental concepts in git which is git commit and git branch. Let’s understand these two terms respectively. What is a Commit? Commit is defined as the location where the code and its changes are stored.  In git merge, looking at the end diagram, one can make out Commit A and B came from the feature branch. However, in the git-rebase diagram, it is difficult to understand where commits A and B came from. Therefore, we do git merge when we want our team to understand logs in a way where they can identify where each commit is coming from. We use Git Rebase when the logs of the repository will not be referred by anyone else. To summarise, we can use Git Rebase, when we are working on branches, which cannot be seen by other developers. And we use Git Merge when the target and source branch can be viewed by other developers. How can Git Rebase and Git Merge be used together? Let us take an ex...

AWS Lamda Cold Start

AWS Lambda provides many benefits for developers, including scalability, flexibility, faster release times, and reduced cost. However, also comes with limitations such as cold starts. Cold starts can increase the latency of serverless applications How Does AWS Lambda Work? Lambda functions run on their own container. When you create a new function, Lambda packages it into a new container. This container is then executed on a multi-tenant cluster of managed machines. Before the functions start running, each container is allocated its necessary CPU and RAM capacity. When a function finishes running, the allocated RAM is multiplied by the amount of time the function spent running. AWS charges customers based on the allocated memory and the amount of function run time. AWS Lambda can simultaneously execute many instances of the same function, or of different functions from the same AWS account. This makes Lambda suitable for deploying highly scalable cloud computing solutions. What Is an A...
