In go language a long type variable is not a separate data type but it is an extension made from the integer data type to store even larger types of integers. The main difference between an int data type and long data type is that int data type is 32 bits whereas long data type is 64 bits. Syntax func typeOf (x interface{}) The typeOf() function is used to get the type of any variable. This function is present in reflect package and it takes the variable whose type is to be determined as an argument. The function then ... Read More

Insertion sort is a simple sorting algorithm that works similarly to the way you sort playing cards in your hands. The array is virtually split into a sorted and an unsorted part. The elements from unsorted arrays are picked and placed at the correct positions in unsorted arrays, as a result, the array becomes sorted. Here we are going to learn different approaches to sorting an array in descending order using insertion sort in go programming language. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. It takes number ... Read More

Cyclically means that in every cycle we wish to move the array elements by one position till we get the original array again. Cyclic permutation can be useful in various matrix manipulation and linear algebra operations. In this article, we are going to see different examples to permute the elements of the array cyclically using go programming language. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. It takes number of arguments. The first argument is the array to which we wish to add the values followed by the ... Read More

In this article we will write a go language program to check if a given number is finite or not. The program uses IsInf() and IsNaN() library functions in order to check whether numbers are finite or not. Syntax func IsInf(f float64, sign int) bool IsInf() function is present in the math package. This function takes two arguments one is the floating point number that we wish to check and the other is the sign. The sign is an integer which can be greater than, lesser than, or equal to zero. If the sign is greater than zero then ... Read More

An array in go language is defined as the data structure that is used to store elements in contiguous memory locations. Arrays allow us to search and store elements at constant time. arrays use index to store elements which starts from 0 and goes to n – 1, where n is the length of the array. Method 1: Using An External User-Defined Function The following method, illustrates how we can remove a particular integer element from the array of integers using an external function. Algorithm Step 1 − Import the fmt package. Step 2 − Defining a function named ... Read More

An array in go language is defined as the data structure that is used to store elements in contiguous memory locations. Arrays allow us to search and store elements at constant times. arrays use the index to store elements that start from 0 and goes on to n – 1, where n is the length of the array. Algorithm Step 1 − First, we need to import fmt package. Step 2 − Now, start the main() function. Inside the main() initialize an array of strings. Step 3 − In order to add values to this array we have to ... Read More

What is a 2D array? A two-dimensional array is a collection of data that are arranged in rows and columns. In go we can use the for loops to iterate and print elements of the 2d arrays. Here is an example of the same below − 0 1 2 4 5 6 8 9 10 Method 1: Using For Loops In this method, we will use for loops in golang to iterate over the arrays and catch each element then we will print that element unless the whole array is iterated upon. Algorithm ... Read More

A matrix is a collection of numbers arranged in rows and columns, a two-dimensional array, each of the values of this matrix is known as an element. Here we will use three methods to find the sum of column elements and compare each method for the same using go programming. Here is an example of a matrix and the sum value of it’s columns − The given matrix is − 0 1 2 4 5 6 8 9 7 Sum of elements in column 1 is 12 Sum of elements in column 2 ... Read More

A matrix is a collection of numbers arranged in rows and columns, a two-dimensional array. Here we will use three methods to find the sum of elements and compare each method for the same using Go Programming language. Algorithm Step 1 − Import the fmt package. Step 2 − Now we need to start the main() function. Step 3 − Then we are creating a matrix naming matrix. Step 4 − Print the matrix on the screen using fmt.Println() function. Step 5 − Initialize a new variable called sum of type int to hold the resultant sum. Step ... Read More

What are Objects in Golang? Objects are defined on the structs and store Key-value pairs of data together in go programming. There are numerous methods for producing an object. A struct is a user-defined type that groups together a collection of fields (also known as properties or data members) and methods. A struct can be defined using the type keyword, followed by the struct name and a struct literal that defines the fields of the struct. Method 1: Using a user-defined function Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then we ... Read More
