Golang program to find the duplicate characters in the string
In golang, identifying characters that appear more than once in a string is the first step in finding duplicate characters. To accomplish this, iterate through the string while keeping track of the characters that have already been encountered. Then, before adding a character, determine if it is already in the set of characters that have already been encountered. A character is a duplication if it already exists in the set. Let’s see its execution. Method 1: Using map and a for loop In this method, the program uses a map to keep track of the number of times each character ...
Read MoreGolang program to remove all whitespaces from a string
When we remove whitespaces from a string it means removing blank spaces, tabs, and other white space characters, including newline characters. This can be helpful for parsing user input or working with data in a particular format, among other instances where we wish to clean up or standardize a string before processing it further. There are various ways to eliminate whitespace from a string. A few examples include: Using the TrimSpace function, whitespace characters at the beginning and end of a string are eliminated. Using the Replace function to replace any whitespace in the string with a string that is ...
Read MoreGolang program to show use of super keyword in class
In golang, the "super" term doesn't exist in Go. The "super" keyword is used in object-oriented programming languages to denote the parent class or the class that is being inherited from. It is often used to access parent class methods or properties that the child class has modified. In this article, we will see how to use super keyword in the class with different examples. Method 1: Using child struct and parent struct In this Method, we will learn how to use super keyword in class using child struct and parent struct. Here, a Parent struct is embedded in the ...
Read MoreGolang program to print first letter of each word using regex
A string of characters known as a regular expression (regex or regexp) creates a search pattern. Regular expressions are frequently employed to carry out string matching, sometimes known as "find and replace, " or pattern matching with strings. Input validation, parsing, and other tasks are also possible with them. Regular expressions use special characters and metacharacters to specify the pattern to be matched, and their syntax differs widely between computer languages. Let’s see different Golang examples to get a clear view of the concept. Method 1: Using regex.MustCompile() function In this example, we will see how to print first ...
Read MoreGolang program to remove leading zeros
Removing any zeros that appear at the start of a number or string is referred to as "removing leading zeros" in Golang. Leading zeroes are frequently included for formatting or alignment needs, although they don't convey any significant information. They can be eliminated to improve the number's or string's usability and human-readableness. It's important to keep in mind that leading zeroes can occasionally be crucial for specific applications, such as some financial or scientific ones. Let’s see through this program to get a clear understanding of the concept. In this program we will learn how to remove leading zeros using ...
Read MoreGolang program to compute all the permutations of the string
In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters. A permutation of a string is a distinct string with the same characters but a different ordering of the characters. For instance, the words "abcd" and "dabc" are combinations of one another. Here, in this program we will explore method to find permutation of string and print the output on the console using print statement in Golang. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used ...
Read MoreGolang program to create a multi-line string using '%Q
In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters. The multi-line will be printed using backticks and the output will be printed on the console using fmt package. Let’s see different examples to get a clear understanding of the concept. The fmt employs the verb %q. To print the string in a format that can be securely included inside double-quoted string literals, use the printf function. This guarantees that any special characters, such as newlines, in the string will ...
Read MoreGolang program to splitting into number of substrings
In the Go programming language, a substring is a portion of a string that contains a sequence of characters from the original string. A substring can be obtained in Go by using the slicing syntax on a string value.. strings. Split() can be used in Go (Golang) to divide a string into substrings. The first input to the function is the string to be split, and the second argument is the delimiter that will be used to separate the substrings. A slice of strings containing the substrings is the result of the function. There are other ways to split a ...
Read MoreGolang Program to Check if a string is a valid shuffle of two distinct strings
In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters. In this article, we will learn how to check if a string is a valid shuffle of two strings using different set of examples. The output will be a Boolean value printed on the console using fmt package. Method: Using a for loop with len method In this method, we will learn how to check if a string is valid shuffle of two distinct strings. This program defines a function ...
Read MoreGolang program to replace the spaces of string with a specific character
In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters The first and foremost approach used here is Replace() method which replaces the space with a specific character and many more methods can be applied to solve the problem. The modifies string will be the output printed on the console using fmt package. Method 1: Using strings.Replace() function In this method, the space character (" ") is replaced with the character "-" using the Replace() function. The function is instructed ...
