Pythagorean Quadruple
A group of four positive integers (a, b, c, and d) that satisfy the Pythagorean equation are called Pythagorean quadruples. The equation can be written as: a2 + b2 + c2 = d2 , with ‘d’ being the largest value out of the given numbers. In other words, the square of the fourth integer should be equal to the sum obtained by adding the squares of the previous three numbers. (1, 2, 2, 3) is a Pythagorean quadruplet as (12 + 22 + 22) = (1 + 4 + 4) = (9) = (32). Due to the requirement ...
Read MorePalindromic Selfie Numbers
A number is considered to be a “Selfie Number” if it can be represented using only its own digits and certain mathematical operations. For example, 936 is a selfie number. $$\mathrm{936\:=\:(\sqrt{9})!^{3} \:+\:6!\:=\:216\:+\:720\:=\:936}$$ Here it can be observed that a series of operations are performed on the digits of the original number and the resultant is equal to the original number. Palindromic Selfie Numbers are a special kind of selfie number. They satisfy the selfie multiplicative rule. Consider a number x. Let the number formed by reversing the digits of x be $\mathrm{x^\prime}$. Let y be a ...
Read MoreClosest Numbers from a List of Unsorted Integers
In the following article, we discuss two approaches to find the closest numbers from a list of unsorted integers. Let us first understand what is meant by the term ‘closest numbers’. Closest numbers are the pair(s) of numbers which have the least difference between them. Problem Statement Given a list of distinct unsorted integers, we need to find the pair of elements that have the least difference between them. If there are multiple pairs, we need to find all of them. Furthermore, in the article wherever there is a mention of difference, it means absolute difference. Examples Input: [44, 42, ...
Read MoreDelete a Linked List Using Recursion
Linked List A linked list is a linear data structure in which the elements are stored at non-contiguous memory locations. Each element consists of a node. A node is composed of a data field, which holds the value of the element, and an address field, which points to the location of the next node in the series. The first node of the linked list is referred to as the ‘head’ of the list. The last element of the linked list can be defined as the element which points to NULL. A diagrammatic representation of a linked list is shown below. ...
Read MoreTo Check if a Number is a Munchhausen Number
Munchhausen Numbers are peculiar numbers which possess a unique property. A number is considered to be munchhausen if the sum of the digits of the number, raised to their own power, is equal to the original number. These numbers are uncommon and not many of them are known. If the definition 00 = 0 is used, then 0 can also be considered a munchhausen number. The following article provides a method to determine whether a number is munchhausen or not while keeping in mind these characteristics of munchhausen numbers. Problem Statement The task at hand is to check whether a ...
Read MoreSplitting the slice after the specified separator in Golang
In Golang, there are multiple ways to split a slice after a specified separator. This can be achieved using built-in functions and methods. In this article, we will explore some of the common ways to split a slice in Golang. Using strings.SplitAfter Function The strings package in Golang provides a SplitAfter function, which splits a string or slice of bytes after the specified separator and returns the result as a slice of strings Example package main import ( "fmt" "strings" ) func main() { slice := []string{"apple_", "banana_", "cherry_", ...
Read MoreSplitting the string after the specified separator in Golang
Splitting a string after a specified separator is a common operation in many programming languages, including Golang. In Golang, the strings package provides several functions to split a string after a specified separator. In this article, we will discuss how to split a string after a specified separator in Golang. Using strings.SplitAfter() The strings.SplitAfter() function is used to split a string after a specified separator. It takes two arguments: the string to be split and the separator after which to split the string. The function returns a slice of strings. Example Here's an example code that demonstrates how to use ...
Read MoreSplitting a Slice Separated by the Specified Expression in Golang
In Golang, slices are used to store sequences of elements of the same type. Slicing a slice is a common operation in Golang, but sometimes we need to split a slice based on a specified separator. Golang provides a built-in function to split a string based on a separator, but splitting a slice is a bit different. In this article, we will explore how to split a slice separated by the specified expression in Golang. Using the Strings Package The strings package in Golang provides the Split() function, which is used to split a string into a slice based on ...
Read MoreHow to compare two slices of bytes in Golang?
In Go, comparing two slices of bytes involves checking if each element in both slices is equal. This can be done using a loop or the built-in bytes.Equal() function. In this article, we'll explore both methods and see how to compare two slices of bytes in Go. Using a Loop To compare two slices of bytes using a loop, we can iterate over each element in both slices and check if they are equal. Here is an example − Example package main import ( "fmt" ) func main() { slice1 := []byte{0x01, ...
Read MoreHow to compare times in Golang?
In Golang, it's common to work with time-related operations, such as comparing times. Comparing times is essential when dealing with scheduling, deadlines, and many other scenarios. In this article, we'll explore how to compare times in Golang and provide you with a comprehensive guide. Golang Time Package Golang provides a built-in time package, which offers various functionalities related to date and time. To use this package, you'll need to import it in your code using the following syntax − import "time" The time package provides a Time type that represents a specific time. You can create a Time value ...
