In this tutorial, we will write a go language program to add an element in the array at the beginning of an array. to add an element in the starting of an array we will use for loops and the concept of indexing in arrays. We shall now discuss these methods one by one in this program. Method 1: Using Append() Function Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments and returns the ...

In this tutorial, we will write a go language program to get the last given number of items from an array. We can do this by either using the inbuilt functions in go or using for loops. The first method is more efficient in functionality than the second one but we will discuss both these methods in this program. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments func append(slice, element_1, element_2…, element_N) []T ...

A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. So here we print the right diagonal of square matrix. Square matrix is a matrix in which the number of rows and columns are same. For example 3x3, 5x5, 7x7, etc. In this article, we will learn how to write a swift program to print the right diagonal matrix. Algorithm Step 1 − Create a function. Step 2 − Run for-in loop to iterate through each element of the matrix. Step 3 − Check for ... Read More

In this article, we will learn how to write a swift program to print the left diagonal matrix. A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. So here we print the left diagonal of square matrix. Square matrix is a matrix in which the number of rows and columns are same. For example 3x3, 5x5, 7x7, etc. Algorithm Step 1 − Create a function. Step 2 − Run for-in loop to iterate through each element of the matrix. Step 3 − Check ... Read More

A number is a perfect cube if the result of the three time multiplication of a whole number is the number itself. For example: number 5 is a per Number = 125 125 = 5*5*5 Here 125 is a perfect cube. Number = 98 Here 98 is not a perfect cube. In this article, we will learn how to write a swift program to check whether a number is a perfect cube or not. Method 1: Using user defined function To check if the given number is a perfect cube or not, we create a function that check each number ... Read More

A perfect number is a positive number that is equal to the sum of its factors, excluding the number itself. For example − Number = 6 Proper divisors = 1, 2, 3 Hence, 6 is the perfect number because the sum of its divisors is 6(1+2+3) Number = 10 Proper divisors = 1, 2, 5 Hence, 10 is not a perfect number because the sum of its divisors is 8(1+2+5) In this article, we will learn how to write a swift program to check if the given number is a perfect number or not. Algorithm Step 1 − Create ... Read More

A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc.In this article, we will learn how to write a swift program to calculate the sum of rows of matrix elements. Here we are using the following methods to find the sum of the rows elements − Using nested for-in loop Using in-built function Method 1: Using nested for-in loop Here we use nested for-in loop to find the sum of rows of matrix elements. Algorithm Step 1 − Create a function. Step 2 ... Read More

A matrix is a rectangular array of numbers. Or we can say that a matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. In this article, we will learn how to write a swift program to calculate the sum of matrix elements. So here, using the following methods we calculate the sum of matrix elements. Sum of square matrix elements Sum of any matrix elements For example, we have the following matrix − $\mathrm{Matrix\:=\:\begin{bmatrix}1 & 4 & 5 & 6ewline4 & 7 ... Read More

A matrix is an arrangement of numbers in rows and columns. The matrix can be of various types like square, horizontal, vertical, etc. In this article, we will learn how to write a swift program to calculate the sum of columns of matrix elements. Here we are using the following methods to find the sum of the column’s elements − Using a nested for-in loop Using in-built function Method 1: Using nested for-in loop Here we use a nested for-in loop to find the sum of columns of matrix elements. Algorithm Step 1 − Create a function. Step ... Read More

What is a string and a substring? A substring in Go is a portion of a larger string. It is specified by providing a start index and a length, and it contains the characters of the original string starting at the start index and going up to the specified length. The characters in a substring are still a part of the original string and share the same memory. In Go, a string is a sequence of characters. It is an immutable data type, meaning that once a string is created, it cannot be modified. Strings are enclosed in double quotes ... Read More
