Java Program to Find the GCDs of given index ranges in an array
In the field of data structure, a range query is a pre-processing method to operate on some input data in an efficient manner. A range query is responsible to answer any query of the particular input on any data subset. If we want to copy some data columns from a table we need to maintain an index for that particular dataset. An index is a direct link or a key, which is designed to provide an efficient searching process in a data set. It is mainly used to speed up the data retrieving from a lost data source. In mathematics, ...

Read MoreC++ Program to count of array elements greater than all elements on its left and at least K elements on its right
A string is an object, which represents a sequence of data characters. The strings are the data container which always represented as a text format. It also used to concept, compare, split, join, replace, trim, length, intern, equals, comparison, substring operation. K largest(or smallest) elements in an array using Quick Sort partitioning algorithm. Here is an array R[] with N number of distinct integers. The task is to find that particular element which are strictly greater than all the elements preceding it and strictly greater than at least K elements on its right. The problem states that an array ...
Read MoreCalculating total number of Hours, Days, Minutes and Seconds between two dates in Golang
Calculating the total number of hours, days, minutes, and seconds between two dates is achievable in Golang. In this article, we'll go through how to accomplish this in Golang, along with the necessary libraries and sample code. Calculating the Total Number of Hours, Days, Minutes, and Seconds In Golang, we may utilise the time package to determine how many hours, days, minutes, and seconds are there between two dates. To modify dates and times, the time package offers a number of functions. The total number of hours, days, minutes, and seconds between two dates can be calculated in Go ...
Read MoreBuffered Channel in Golang
A buffered channel in Golang is a particular kind of channel that enables several values to be transmitted and received without blocking. In this post, we'll talk about buffered channels in Golang, their syntax, and some real-world uses. What is a Buffered Channel? In Golang, a channel type that can keep a predetermined number of values before blocking is known as a buffered channel. As long as there is space in the buffer, this permits sending and receiving numerous values without blocking. Any additional attempts to send data will be blocked after the buffer is filled until more room is ...
Read MoreBits Package in Golang
Bits package in Golang has functions for changing a binary number's individual bits. This package is very helpful in low-level applications like networking, cryptography, and bitwise operations. This post will go through the Golang bits package and show you how to utilise it in a real-world application. Introduction to the Bits Package The bits package offers tools for working with a binary number's constituent bits. The "BitArray" type, which represents a series of bits, is the main type in the bits package. An implementation of the "BitArray" type is a slice of "uint64" values, where each "uint64" value has ...
Read MoreBasics of JSON with GoLang
JSON has grown in popularity as a data format for transferring data across apps in recent years. JSON (JavaScript Object Notation) is a compact and simple-to-understand standard for exchanging data. It is widely used in server-to-server communication, mobile applications, and web applications. Its simplicity, concurrency, and scalability make GoLang a powerful programming language. The fundamentals of JSON with GoLang will be covered in this post. What is JSON? JSON is a simple, lightweight data exchange format that is simple for both people and robots to comprehend and generate. It is a completely language-independent text format that adheres to principles that ...
Read MoreBase64 Package in Golang
Base64 package in Golang is a standard library package that offers capabilities for base64-encoding and -decoding binary data. Base64 is a popular method of encoding that enables binary data to be represented using just sharable ASCII letters, making it perfect for transmission over text-based protocols like HTTP and SMTP. We'll look into the Golang base64 package and discover how to encrypt and decrypt data in base64 format using the package's functions. We'll also talk about the best ways to interact with binary data in Golang and examine some typical use cases for base64 encoding and decoding. You ought to be ...
Read MoreAuto Format Go Programming Language Source Code with Gofmt
Let's look at how ‘gofmt’ can automatically style your Go source code in a consistent manner so that it is easier to understand and manage. In order to write readable, maintainable code, it must be formatted correctly. Go source code can be formatted using the 'gofmt' command-line tool. Using a set of rules and conventions, this programme automatically reformats your Go code to make it simpler to read and comprehend. What is Gofmt? A command-line tool called Gofmt is used to format Go source code consistently. Your code's space, indentation, and line breaks are automatically adjusted to make it easier ...
Read MoreAtomic Variable in Golang
Atomic Variable in Golang offer an alternative to use locks or other synchronisation primitives to execute atomic operations on shared variables. When programming concurrently, synchronisation and mutual exclusion are essential to ensuring that threads or processes can access shared resources without interfering with one another. The fast and scalable synchronisation and coordination of concurrent access to shared variables is made possible by the use of atomic variables. What is an Atomic Variable? An atomic variable is a shared variable that may be read from and written to simultaneously by several goroutines while still ensuring that all actions are atomic. The ...
