How to Find Whether the given Number is PRIME or not using Recursion in Golang?
In mathematics, there are numbers that can be divisible by 1 or by itself, and such numbers are called Prime numbers. For example, 2, 3, 5, 7 … etc. In programming, we can create a program to check number is prime or not. In this article, we will use the concept of recursion which we call the function within the function to create a program to check number is prime or not. Example 1 In this example, we are going to create a recursive function with two parameters one is the number and another one is the divisor. The ...
Read MoreHow to find the Tangent of a given Radian Value in Golang?
The ratio of the radian’s adjacent side and the opposite side is known as the tangent of the given radian. Golang language has many packages with predefined functions that the developer can use without writing the complete logic. To perform the mathematical operations and logic we have a math package in Golang. We will use this package only to find the Tangent of a given radian value. We will also see how to import the package and also how to call a function this package consists of by writing a Golang code. Tangent Definition Tangent is a function that ...
Read MoreHow to Check Whether a Number is Even or Odd in Golang?
In this tutorial, we are going to learn how we can check whether the number is even or odd. The number that can be divisible by 2 is an even number and the number that is not divisible by two is an odd number. This tutorial includes three different ways to achieve this Moulous Operator − In the first method, we are using the modulus (%) operator. This operator is used to find the remainder of two numbers. In our case, we will do the modulus of the number with 2 and if it returns 0 then ...
Read MoreHow Does One Install Pip in a Docker Container using a Dockerfile?
In this tutorial, we are going to learn how we can install pip in a Docker container using a Dockerfile. This tutorial will cover the creation of the Dockerfile and then we will see the docker command to build a docker image from the Dockerfile, and in last we will see the docker command to run a container based on that image and see whether PIP is installed properly or not. Prerequisites There are some prerequisites to creating and building the Dockerfile as mentioned below. The stable version of Docker should be installed. Create a file in any folder ...
Read MoreGolang Program to Sort an Array of 0’s, 1’s and 2’s
In Golang, like other programming languages, we can code the logic to sort an array that has 0’s, 1’s, and 2’s as elements. Sorting means assigning the data either in increasing order or in decreasing order. This is one of the famous questions on the array asked in interviews. There can be two approaches to achieve this that we are going to explore one by one. For example, we have an array 2, 1, 0, 0, 1, 2, and after sorting the array will look like 0, 0, 1, 1, 2, 2. Method 1 In this example, we are going ...
Read MoreGolang Program to Implement Linear Search Algorithm
In programming, to search for anything from an array, linked List, or from any other data structures we have a few search algorithms, one of which is Linear search. In the linear search, we iterate over the data structure from starting and search for the element till the last index. The advantage of a linear search algorithm is that we can perform this search of both sorted and unsorted data. The disadvantage is that for sorted or unsorted both kinds of data it will take the same amount of time to find an element. For example, we have an array ...
Read MoreGolang Program Right View of Binary Tree
In programming, there is a coding problem of binary tree that gets asked very frequently in interviews and the problem statement is to find the right view of a binary tree. If we try to understand the problem statement more than what exactly the right view is then we can explain it in a way that all the nodes are visible when you see them by standing on the right side of the tree. Illustration Let us understand more with the help of an example. Suppose we have a below tree and if we stand on the right side ...
Read MoreHow to create a Function with Arguments but without a return value in Golang?
This tutorial will teach us how to create a function with arguments but without a return value. This tutorial involves a gist about the function, and syntax for the function with argument and without return type in Golang, then last we will see two different examples of a function with arguments but without a return type. In the first example, we are going to print the argument passed in the function with the respective statement. In the other example, we are going to add the numbers passed as arguments and print the sum in the same function. Function with argument ...
Read MoreHow to check whether a number is Positive or Negative in Golang?
In this tutorial, we will learn how to check whether the number is positive or negative. This tutorial includes two ways to achieve this by using the built-in function Signbit() present in the math library. Another way is to use the relation operators using which we can compare a number with zero and predict whether the number is positive or not. Method 1: Using Signbit() function In this example, we are going to use the built-in function Signbit() present in the math library to check whether the number is positive or negative. Syntax Signbit() is a function in math library ...
Read MoreHow to create a Function with Arguments and a return value in Golang?
This tutorial will teach us how to create a function with arguments and a return value. This tutorial involves a gist about the function, and syntax for the function with an argument and a return type in Golang, then last we will see two different examples of a function with arguments and with a return type. In one example we will return the sum of two numbers and in the other one, we will return the area of the circle. Functions in the Programming language. Let us first see what function is. The function is a subset of a program ...
