A doubly linked list could be an information structure where each node contains a reference to both its previous and following nodes. The program points to preserve the sorted arrangement of the linked list whereas inserting an unused node. In this article, we will learn to create a Golang program that focuses on inserting a node into a sorted doubly linked list. Here we are going to use the method insertNode along with examples to elaborate on the concept. Syntax func insertNode(head *Node, value int) *Node This Syntax represents a function named "insertNode" that takes a pointer to the ... Read More
In Golang, the recovery mechanism provides a way to deal with panic and recover from it. Panic is an unexpected error that can cause the program to terminate. In this article, we are going to discuss what is recovered in golang. Here we are going to use two different methods: using handlePanic as well as the main() function along with examples to elaborate the concept. Syntax recover() In this Syntax, The handlePanic function is used in Go to recover from panics. It checks if a panic occurred using the recover() function, which returns the value passed to panic(). If ... Read More
In Go, race conditions occur when goroutines simultaneously read and write to the same shared memory space without synchronization mechanisms. This can cause data corruption, inconsistent states, or crashes.In this article, we are going to discuss race conditions in golang. Here we are going to use two different methods: Synchronization with WaitGroup as well as Synchronization with Mutex along with examples to elaborate the concept. Syntax sync.mutex() it is used to create a new mutex variable. The sync.Mutex type provides a way to control access to shared resources by acquiring and releasing locks mutex.Lock() This method is ... Read More
In this article we are going to discuss an overview of Benchmark testing. Benchmark testing is a basic portion of program optimization to grade the execution and productivity of code. In Golang, benchmark testing is backed through the built-in testing bundle. Here we are going to use the Benchmark function along with examples to elaborate on the concept. Syntax time.duration() This function is used to represent the time interval in go language. It allows the user to work with time durations. time.sleep() We use this function to stop the execution of a go language program for a specific ... Read More
The purpose of this interface is to provide a contract for implementing cache functionality in various data structures or systems. The Set method is responsible for storing a value in the cache with a specified key, while the Get method retrieves the value associated with a given key from the cache. In this article, we will create an interface called Cache that defines two methods: Set and Get. Here we are going to use two different methods − Get(key string) interface{} as well as Set(key string, value interface{}) along with examples to elaborate the concept. Syntax Set(key string, value interface{}) ... Read More
Radix sort is a non-comparative sorting algorithm that works by distributing elements into different buckets based on their significant digits. In this article, we will explore a Golang program that implements radix sort for sorting integers in descending order. Here we are going to use three different methods: Getmax, countsort, and radixsort along with examples to elaborate the concept. Syntax func getMax(arr []int) int The Syntax "func getMax(arr []int) int" defines a function named "getMax" that takes a slice of integers as a parameter and returns an integer value. func countSort(arr []int, exp int) The Syntax "func countSort(arr ...

A binary heap is a specialized tree-based data structure that satisfies the heap property, where the key of each node is either greater than or equal to (in a max heap) or less than or equal to (in a min heap) the keys of its children. In this program, we utilize a linked list to represent the binary heap. In this article, we will learn how to develop the Golang program to implement a binary heap using a linked list. Here we are going to use four different methods singly linked list, doubly linked list, custom node struct, and slice-based ... Read More
Red Black Tree is a self-balancing binary search tree with additional properties that ensure a balanced tree structure and efficient operations. The delete operation in a Red Black Tree involves rearranging the tree and maintaining the Red Black Tree properties after removing a node. Here we are going to use three different methods:deleteNode method, delete method, and successor transplant method along with examples to elaborate the concept. In this article, The Golang program implements the deletion operation in a Red Black Tree data structure using Golang. Syntax func (t *RedBlackTree) Delete(key int) The Syntax "func (t *RedBlackTree) Delete(key int)" ... Read More
CSV (Comma−Separated Values) is a plain text file format used to store tabular data. It is a widely supported and commonly used format for exchanging data between different applications, particularly in spreadsheet software like Microsoft Excel, Google Sheets, and others. When working with CSV files, it's essential to be mindful of the delimiter used, handle special characters appropriately, and ensure data integrity and consistency. Steps to Export Excel Data to CSV To export Excel data to CSV (Comma−Separated Values) format, you can follow these steps: Method 1: Save As CSV Step 1: Open the Excel file containing the data you ...

Excel is a powerful tool that offers a variety of functions for data manipulation and analysis. Supposing you have a lot of pictures in your workbook and want to save them to a specific folder at a time, usually, you can copy and paste the pictures one by one manually for saving, but it is time−consuming to copy and paste them repeatedly like this. Here, I will introduce you some tips to solve this job. With the Excel built−in Save As function, you can save a workbook as Web Page to save all pictures including charts, shapes and other objects ... Read More
