Definition: A number is that is greater than 2 and divisible only by itself and 1.Examples: Prime numbers are 2, 3, 5, 7, 11, 13, 113, 119, ..., etc.Approach to solve this problemStep 1: Find square root of the given number, sq_root = √numStep 2: If the given number is divisible by a number that belongs to [2, sq_root], then print “Non Prime Number”Step 3: If not divisible by any number, then print “Prime Number”ProgramLive Demopackage main import (    "fmt"    "math" ) func checkPrimeNumber(num int) {    if num < 2 {       fmt.Println("Number must be greater than 2.")       return    }    sq_root := int(math.Sqrt(float64(num)))    for i:=2; i

Bubble Sort is a sorting algorithm that works by swapping the elements that are in the wrong order. In multiple passes, it checks if the adjacent elements are in the right order (increasing) or not.The Time Complexity of the Bubble Sort is O(n^2) since it takes two nested loops to check the adjacent element.For example, let’s take the following unsorted array −22 15 11 45 13Bubble Sort Algorithm first traverses the whole array and then in another loop checks if the adjacent elements are in order or not.Thus, after sorting the elements will be, 11 13 15 22 45AlgorithmIn two ...

ExamplesA1 = [2, 4, 6, 7, 8, 10, 3, 6, 0, 1]; Minimum number is 0;A2 = [12, 14, 16, 17, 18, 110, 13, 16, 10, 11]; Minimum number is 10;Approach to solve this problemStep 1: Consider the number at the 0th index as the minimum number, min_num = A[0].Step 2: Compare min_num with every number in the given array, while iterating.Step 3: If a number is smaller than min_num, then assign that number to min_num.Step 4: At the end of iteration, return min_num;ProgramLive Demopackage main import "fmt" func findMinElement(arr []int) int {    min_num := arr[0]    for i:=0; i

In this article, we will learn about how to install and configure Go (golang) which is developed by Google and its open source programming language. It’s a simple, efficient and reliable programming language for development with minimalist.PrerequisitesA CentOS machine installed.A non-root user with Sudo permission on the CentOS machine.Downloading and Installing the GOThe Go (golang) is not up to date on the CentOS repository, so we will manually download and install the package directly from the Go lang website and also make sure that we have the latest version which is compatible with our system architecture.Let’s move to the writable ...

Docker is an open-source project that automates the deployment of application inside the software container. The container allows the developer to package up all project resources such as libraries, dependencies, assets etc. Docker is written in Go Programming language and is developed by Dotcloud. It is basically a container engine which uses the Linux Kernel features like namespaces and control groups to create containers on top of an operating system and automates the application deployment on the container.Installing DockerBefore install Docker, it should required updated packages. To update the packages, use the following command –$ sudo apt-get updateUse the following ... Read More
