Golang Program To Sort An Array
In this tutorial, we will see to write a go language program to sort an array using three different methods. Sort An Array Of Integers Using User-Defined Functions The following code illustrates how we can sort an array of elements in golang using user-defined functions. Algorithm Step 1 − Importing the fmt package. Step 2 − Defining a function named sortArray() which will sort the given array. Step 3 − Pass the array to be sorted as an argument to this function. This function uses two for loops to iterate over the array. Step 4 − If ...
Read MoreGolang Program To Rotate Matrix Elements
In this article, we will write a go language program to rotate given matrix element. Rotate A Matrix Using An External Function The following code illustrates rotating a matrix anticlockwise by 90 degrees any number of times. Algorithm Step 1 − Import the fmt package. Step 2 − Create a function to rotate the array elements. This function takes the array to be rotated as argument. Step 3 − Also pass the number of times the array is to be shifted as argument. Further, initialize an empty matrix to hold the final result. Step 4 − In ...
Read MoreGolang Program To Remove Duplicate Elements From An Array
In this tutorial, we will see to write a go language program to remove duplicate elements from an array. By removing duplicate entries, we mean that we wish to write a program that will remove a value repeating multiple times. Remove Duplicate Values From An Array Using An External Function The following code illustrates how we can remove duplicate values from an array using a user-defined function. Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Now, make a function named removeDuplicate() that accepts an array as an argument and returns an array ...
Read MoreGolang Program To Remove All Occurrences Of An Element In An Array
In this tutorial, we will see to write a go language program to remove all occurrences of an element in an array. Removing occurrences from an array means that we wish to remove an entry completely from the array. Remove All Occurances Of An Element In An Array Using External Function The following code illustrates how we can remove all the occurrences of an element in an array by using a user-defined function. Algorithm Step 1 − Import the fmt package. Step 2 − Defining a function named removeOccurrence(). Step 3 − In this function, we are checking ...
Read MoreGolang Program To Print Upper Star Triangle Pattern
In this tutorial, we will write a program to print an upper star triangle pattern in go language. In an upper star triangle pattern, there can be only one star printed in the first row and the base must be at the bottom. Printing Upper Star Triangle Pattern In Go Programming Language Algorithm Step 1 − Import the fmt package. Step 2 − Start the main function. Step 3 − In the next step, we need to initialize the integer variables viz i, j, k, and rows. The row variable contains a number of rows to be printed ...
Read MoreGolang Program To Interchange The Diagonals
In this article, we will write a go language program to interchange the diagonal elements of a matrix. Exchange the diagonal elements of a matrix using an external function In this program, we will write a go language program to interchange the diagonal elements of a 3 X 3 matrix using a user-defined function. Algorithm Step 1 − Import the fmt package. Step 2 − Create a function to interchange the diagonal elements of the matrix. In this function, we have defined two variables of integer type and assigned values to them. Step 3 − Use for loop ...
Read MoreGolang Program To Interchange Elements Of First And Last In A Matrix Across Rows
In this article, we will write a go language program to interchange elements of first and last row in a matrix. Interchange Elements Of The First And Last Row In A Matrix Using An External Function In this program, we will write a go language program to interchange the elements of the first and last row of a 3 X 3 matrix using an external function. Algorithm Step 1 − Import the fmt package. Step 2 − Create a function to interchange the first and last row of a matrix. In this function, we have defined two variables of ...
Read MoreGolang Program To Interchange Elements Of First And Last In A Matrix Across Columns
In this article, we will write a go language program to interchange elements of the first and last column in a matrix. Interchange Elements Of The First And Last Column In A Matrix Using An External Function In this program, we will write a go language program to interchange the elements of the first and last column of a 3 X 3 matrix using an external function. Algorithm Step 1 − Import the fmt package. Step 2 − Create a function to interchange the first and last columns of a matrix. In this function, we have defined two variables ...
Read MoreGolang Program To Find Common Array Elements
In this tutorial, we will see to write a go language program to find common elements in two arrays. Find Common Array Elements Using User-Defined Function The following code illustrates how we can find the common elements in two different arrays of strings. Algorithm Step 1 − import the fmt package. Step 2 − Define a function named intersection() that accepts the two arrays as arguments and returns the resultant array as an output to the function. Step 3 − Create an empty array of strings called out and a map called bucket. Step 4 − Use for ...
Read MoreWhat does "Fatal error: Unexpectedly found nil while unwrapping an Optional value" mean?
This error is very frequent as you can see many times while writing code. Don't worry, you will understand this error in detail in this article. Before jumping to the cause of this error, let's understand what is optional in Swift. Optional Initially, when we receive a value from another source, such as the backend server, it might contain a valid value or nothing at all. In that case, you use optionals that represent a variable with two possible situations: either a value or no value at all. var possibleNumber = "450" var convertedNumber = Int(possibleNumber) In the above ...
