Golang program to find the frequency of character in a string
String in Golang is a collection of characters. Since strings in Go are immutable, they cannot be modified after they have been produced. Concatenating or adding to an existing string, however, enables the creation of new strings. The frequency of a character means the number of times a character is appearing. Syntax map() To keep track of how frequently each character appears in the input string, the built-in map data structure in Go is used in example below. The map is an unsorted collection of key-value pairs with unique keys and variable types of values for the values. func ...
Read MoreGolang program to iterate through each character of string
A string in Golang is a collection of characters. Since strings in Go are immutable, they cannot be modified after they have been produced. Concatenating or adding to an existing string, however, enables the creation of new strings. A built-in type in Go, the string type can be used in a variety of ways much like any other data type. Syntax func len(v Type) int The len() function is used to get the length of any parameter. It takes one parameter as the data type variable whose length we wish to find and returns the integer value which is ...

A string in Golang is a collection of characters. Since strings in Go are immutable, they cannot be modified after they have been produced. Concatenating or adding to an existing string, however, enables the creation of new strings. A built-in type in Go, the string type can be used in a variety of ways much like any other data type. Syntax strings.Join(words, ” ”) A slice of strings can be joined together with a separator using the join method. Two arguments are required by the function: a slice of strings, and a separator string. It gives back a single ...
Read MoreGolang program to clear the string buffer
When a string buffer is cleared, all of the data that was previously stored inside the buffer is deleted. This can be done for a variety of reasons, including when you want to reuse the buffer for fresh data or when the data that is currently in the buffer is no longer required. Here we will understand different techniques of clear a string buffer using go programming language Syntax Reset() Any accumulated data is discarded and the buffer is reset to zero using the Reset() method. The old buffer is essentially replaced with a new one and the old ...
Read MoreGolang program to show data hiding in class
In Golang, data hiding is a practice of preventing external code from accessing or changing a class’s members. This is accomplished by designating the class's members as private, which restricts access to or modification of them to the class's methods only. This is a crucial idea in object-oriented programming since it ensures the data's integrity and the class's proper operation. Syntax struct A struct is a composite data type used in the Go programming language that enables you to bring together related values of various types, such as a collection of fields or a collection of methods. Similar to ...
Read MoreAvoid These Mistakes While Learning Java
Java is one of the most popular programming languages in the world and is the language of choice for many developers and coders. With its wide variety of uses, including web development & mobile app development, it's no wonder that so many people are eager to learn how to work with Java. Java is used to develop various applications, from small desktop programs to large enterprise applications. Learning Java can be a great way to expand your skills and create applications that can have a real impact. The Unrivalled Versatility and Robustness of Java Java has become one of the ...
Read MoreSwift Program to Print object of a class
In this article, we will learn how to write a swift program to print object of a class. A class object is known as an instance of a class. For example, colour is a class then obj1, obj2, obj3 and obj4 are the objects from the class. A class can have multiple objects. Syntax var objectname = Classname() Here, using the above syntax we can create an object of a class. Algorithm Step 1 − Create a class with properties and a constructor. Step 2 − Create a function to print the object of the given class. Step ...
Read MoreSwift Program to fill an array with a specific element
In this article, we will learn how to write a swift program to fill an array with a specific element. An array is used to store elements of same data type in an order whereas a set is used to store distinct elements of same data type without any definite order. In an array, every element has an index. The array index is start from 0 and goes up to N-1. Here N represent the total number of array elements. We can fill an array with a specified element using the following methods − Using user defined function Using ...
Read MoreGolang program to get maximum and minimum from a slice
In this article, we will see how to fetch maximum and minimum elements from a slice. A slice is a sequence of elements just like an array. An array is a fixed sequence of elements whereas a slice is a dynamic array, meaning its value is not fixed and can be changed. Slices are more efficient and faster than arrays moreover; they are passed by reference instead by value. Let us understand this basic concept using different set of examples and algorithms based upon them. Method 1: Using the Helper Function In this method, we will learn how to get ...
Read MoreGolang to check if a slice is empty
In this article, we will check if the slice is empty or not using a variety of examples. A slice is a sequence of elements just like an array. An array is a fixed sequence of elements whereas a slice is a dynamic array, meaning its value is not fixed and can be changed. Slices are more efficient and faster than arrays moreover they are passed by reference instead by value. Let’s learn through examples how it can be executed. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. ...
