The Least Frequently Use aka LFU is a concept of page memory management, can also be used as a replacement algorithm. This process take a lead we the particular page needs a replacement when a new page is on the way by the process. LFU is one of the page replacement policy where an user can replace the least frequency of a particular operation page. If the page frequency is same in a process, then it will come first on the replacement list. Here we will take a page sequence of an array of pages denoted as pages[], whose length ... Read More
Generating random numbers is a common task in many programming applications. In Go, we can use the math/rand package to generate random numbers. In this article, we will explore how to get a random number of type float32 in Go. Using The Rand Package The math/rand package in Go provides a simple way to generate random numbers. We can use the Float32() function to generate a random number of type float32. Example Here's an example − package main import ( "fmt" "math/rand" "time" ) func main() { ... Read More
Getting the current date and time is a common task in many programming applications, from logging events to scheduling tasks. In this article, we will explore how to get the current date and time in various formats in Golang. Using The Time Package The time package in Golang provides a simple way to work with dates and times. We can use the time.Now() function to get the current date and time in the local timezone. Example Here's an example − package main import ( "fmt" "time" ) func main() { ... Read More
Generating random strings or characters is a common task in many programming applications, from generating random passwords to generating unique IDs. In this article, we will explore how to generate random strings or characters in Golang. Using the math/rand Package The math/rand package in Golang provides a simple way to generate random numbers and strings. To generate a random string, we can first generate a random number and then convert it to a string. Example Here's a simple approach − package main import ( "fmt" "math/rand" "time" ) const ...

In many programming applications, we need to generate an array of unique random numbers. This can be useful for tasks such as creating unique IDs or selecting random items from a list without repetition. In this article, we will explore how to generate an array of unique random numbers in Golang. Using The math/rand Package The math/rand package in Golang provides a simple way to generate random numbers. However, by default, the random numbers generated by the math/rand package are not guaranteed to be unique. To generate an array of unique random numbers, we need to add some extra logic. ...

Race conditions can be a serious problem for developers working with concurrent programming. When multiple threads or processes access a shared resource simultaneously, they can create unpredictable and potentially dangerous results. Fortunately, the Go programming language provides a number of tools for dealing with this issue, including atomic functions. In this article, we'll take a closer look at how to fix race conditions using atomic functions in Go. Understanding Race Conditions Before we dive into atomic functions, let's review what race conditions are and why they're a problem. A race condition occurs when two or more threads or processes access ... Read More
In Golang, structs are a powerful and essential feature that helps in organizing data and improving code readability. A struct is a composite data type that groups together zero or more values of different types. It is a user-defined type that can be customized according to the programmer's needs. Sometimes, when working with large codebases, it can become difficult to keep track of the different types of structs being used. In this article, we will discuss how to find the type of struct in Golang. Using the "reflect" Package The "reflect" package in Golang provides a way to inspect types ... Read More
In mathematical calculations, trigonometric functions such as sine (sin) and cosine (cos) are commonly used. In Go programming language, you can find the sin and cos values of a number using the math package. In this article, we will discuss how to find the sin and cos values of a number in Golang. Steps to Find the Sin and Cos Value of a Number in Golang Import The Math Package To use trigonometric functions in Go, you need to import the math package. You can do this by using the import statement − import "math" Define The Number Define ... Read More
Subnetting Subnetting is the technique of dividing a huge network into many smaller parts, these logical divisions in an IP network reduce the network traffic and also achieve better performance of the network path. This is used in large organizations when many host devices are connected to a single network where the routing process is carried out during traffic and also increases security. Each device connected to the subnet communicates with one another by using routers. An IP address is used to classify devices on the network which has two parts, the first part represents a network of the address ... Read More
Multicast and broadcast are two often used terms in computer networks and refer to two different methods of transferring data from one source host to multiple destination hosts. Multicast means sending data from one source host to a particular group of hosts, while the broadcast is sending a data packet to all the hosts which are present in the same network. The same network means the network of the source host. In this article, we will be exploring the differences between the broadcast and Multicast in detail, as their benefits, drawbacks, and the situation in which one method is preferred ... Read More
