A[i] in array is implemented as *(A+i) , For example if you have an array of integers and each integer takes 4 bytes. Lets say starting memory address is 100 then memory locations for each element would be 100,104,108,112,116,…… But If Array index starts with 1 then A[i] will be…

You will be provide with a number and you need to find out the column name. For example Input Output 26 Z 51 AY 52 AZ 80 CB 676 YZ 702 ZZ 705 AAC By excel column numbers to name signifies, for 1 — A, 2 — B, 3 —…

In this problems we need to find out that particular time when there were the maximum guests. Let’s say we have maintained a log for arrival and departure and from there we need to figure out the number of guest present at particular interval. For example — Input -> arrival[]…

What is Continuous Delivery? Continuous delivery (CD) is an approach in which teams produce software in short cycles, ensuring that the software can be reliably released in small intervals of time safely and quickly in a sustainable way. It aims at building, testing, and releasing software with greater speed and frequency. …

An empty tree is height balanced. A non empty binary tree T is balanced if Left subtree of T is balanced Right subtree of T is balanced The difference between heights of left subtree and right subtree is not more than one. This above height balancing scheme is used in AVL trees. Get height of right and left tree. return true if difference between height is not more than one. class BinaryTree{ Node root; boolean isBalanced(Node node){ int lh; int rh; if(node == null) return true; lh = heigh(node.left); rh = height(node.right);

So basically we have two methods by which we can implement queue using stacks. By Making Enqueue operation costly By Making Dequeue operation costly Let’s see which one we should choose. Method 1: By making enqueue operation costly. This method makes the oldest element always at the top of stack…

I have taken a course on udemy for microservices architecture and I am going to describe the case study given over there. We will go through the main steps of architecture process: Functional Requirements Non Functional Requirements Mapping the components Define communication pattern We are going to discuss Library Management…

My assumptions are you have basic knowledge of JavaScript. Getting Started To get started create a new folder and call it hello_world. $ mkdir myapp $ cd myapp //if windows users they can directly create the folder, and after getting inside the folder they can open the command prompt from there, which will get…

In my previous blog I have discussed the problems caused by Monolith and SOA. Microservices solve these problems. 19/180: Microservice & Architecture | by Navneet Ojha | Apr, 2021 | Medium Single Technology Platform With monolith all the components must be developed using the same development platform. And that same development platform is…
