Graph is a data structure that consists of edges or we can say nodes and vertices. Vertices are the lines between the nodes. To traverse all these nodes we have different traversal algorithms. In this article, we will discuss, Breadth − first search or we can say BFS. In Breadth − first search, we first start from one node and move to another till the dead end comes. Example If we start from node 1 then it will first visit node 2 and node 4 first. Then from node 2, we will visit node 3. In this way, the ... Read More
In programming, to make the code more modular, usable, and readable we break the code into different functions. For example, we have to swap two numbers at different places so instead of swapping in place we create a different function and call it everywhere. In some use cases, we need a function that returns multiple values at once. For this, we have a data structure called arrays in programming that is nothing but a collection of multiple values of the same type. In this tutorial, we are going to learn about how to return an array in function as an ... Read More
In programming, to make the code more modular, usable, and readable we break the code into different small blocks and these blocks are known as functions. A string is a data structure consisting of a set of alphabets. In solving any programming problem we want that the function should return some set of alphabets then we create a string in the function that the function returns in the end. This tutorial will explain this concept with the help of two examples. In the first example, we will define two strings and create a function that will return the string ... Read More
In this article, the given task is to find the number of unique words in a text file. In this Python article, using two different examples, the approaches to finding the unique words in a text file and their count are given. In the first example, given words from a text file are fetched, and then their unique set is made before counting these unique words. In example 2, first the list of words is created, then it is sorted. After this from this sorted list, the duplicates are removed and finally, the unique word left in the file ... Read More
In programming, to make the code more modular, usable, and readable we break the code into different functions. For example, we have to sort some set of numbers for which we will create a separate function. For this, we have a data structure called arrays in programming that is nothing but a collection of multiple values of the same type. Once the array of numbers is sorted then at the end of that function we have to return the sorted elements so in this article we will see how to return the array. Syntax The syntax to declare a function ... Read More
In this Python article, the given task is to get the frequency of the elements which are common in a list of strings. Sometimes the list to be analyzed using Python is available in an Excel file. To get this list from Excel, a module called openpyxl is used. In this Python article, using three different examples, the ways of getting the frequency of the items which are repeated in a list of strings are given. In example 1, the frequency of the characters which are common in a list of strings is found. In the next two examples, ... Read More
In this tutorial, we are going to learn about how to pass a string in function as an argument in Golang. In programming, to make the code more modular, usable, and readable we break the code into different small blocks and these blocks are known as functions. If you have created a string of alphabets and you want to perform some operations on the string then you need to pass that string to the function by passing it as an argument. This tutorial will explain this concept with the help of two examples. In the first example, we will ... Read More
In this article, the given task is to add the first and the last digit of an integer. Now the integer can be very small or it can be a big number. So, these programs will have two parts. First, we need to find how big the integer is and then get the first digit from it. The second part will be to get the last number from the given integer which can be done easily by dividing the number by ten and finding the remainder. In this Python article, using four different examples, the approaches to adding the first ... Read More
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 More
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 More
