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.TrimSpace() To eliminate leading and trailing white space from a string, use the strings.TrimSpace() function. Algorithm Step 1 − Create a package main and declare fmt(format package) package. Step 2 − Create a main function. Step 3 − Using internal ... Read More

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 More

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 More

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.

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find mean and median of an unsorted array in Java. Mean of an array can be derived by calculating the average value of all the elements present inside the array. Mean= (sum of all elements present in array) / (total number of elements present) Median of an array represents the middle element present in an odd number sorted array and if the sorted array consists of even number, then median can be ...

An array is a linear data structure in which elements are stored in contiguous memory locations. As per problem statement, we have to alter two array elements with each other. Altering two array elements in other words can also be called swapping or exchanging two elements with each other Let’s explore the article to see how it can be done by using Java programming language. To Show you Some Instances Instance-1 Suppose we have the below array = [10, 2, 3, -5, 99, 12, 0, -1] Now if we swap the 5th and 8th elements, Then, we have the new ... Read More
