Introduction A queue is an abstract Data type that inserts elements from the Rear end and removes them from the Front end. There are three types of queues: Simple Queue, Priority Queue, and Circular Queue. In this tutorial, we understand why we cannot wrap around a Priority queue and the reasons for it. Priority Queue It is a unique queue that is not based on the FIFO principle for Queue operations. What makes it unique? It is the priority of its elements for removing or deQueue. Each element of the priority queue has some priority and they are removed based ... Read More
Introduction In this tutorial, we will learn about the in-memory queue in the data structure. A queue is a general data structure that inserts and removes elements with some pattern. It uses the First In First Out approach for its processing. An array and linked lists are used to implement a queue. In-Memory Queue A queue can be visualized as a continuous memory (using an array queue) for storing data types. It is stored in secondary memory. In-memory Queue is different from a simple queue only in terms of its storage area. It is stored in the RAM of your ... Read More
Introduction A queue is a linear data structure that follows the FIFO principle for inserting and removing elements and has no close ending. It is functional on both ends. In this tutorial, we will learn how to turn a queue into a priority Queue and understand the meaning of queue and priority queue in the data structure. What is Queue? Queue in data structure resembles the queue in real life and is used to handle multiple data. It is an ordered list in which elements are entered on the rear end and removed from the front end. In this, the ... Read More
Introduction Queue is a linear data structure that uses the FIFO approach for inserting and removing its elements. It can be implemented by using arrays and linked lists. In this tutorial, we will analyze the time and space complexity of array based queue for its different operation. Queue Implementation Using Array The principle of Queue is its FIFO approach and it states that the element that enters first in the Queue will be the first to be removed from it. Its elements are inserted at the Rear end. Queue elements are removed from the Front end. The real-life example of ... Read More
Introduction The queue is a linear data structure that follows the FIFO approach to insert and extract its data. A priority Queue is a structured Queue, where all data have some priorities for their processing. In Java, a queue or priority queue is an interface. In this tutorial, we will examine whether we should declare a queue or priority queue as a Priority Queue in Java. Queue A Queue in Java is an interface and that interface belongs to java.util package. The queue interface extends the Collection Interface and this interface has several methods. Queue uses FIFO (First In First ... Read More
Card-style design is better than others in terms of functionality and aesthetics. To suit the needs of different screen sizes, the card design can assist users focus on specific content very easily, as well as enabling designers to put up the content reasonably and clearly throughout design.

Golang has a large range of internal packages to work with the directory. The directory in which the application is operating is known as the current working directory. Here we can use the OS packages as well as the path/filepath package of Golang to get current working directory. In the OS package we can use os.Getwd() function to the current working director. Whereas in path/filepath package we can use filepath.Abs and filepath.dir to get the filepath of the current working directory. Method 1: Using os.Getwd() function This method uses the os.Getwd function from the os package to get ... Read More
In go we can use io and os package to perform various operations with file. In this article, we are going to use ioutil.readfile function to read the file and then the string function to convert the file data to string. From OS package we are going to use os.open to open the file and use string operation to convert the data to string. Method 1: Using io/ioutil package In this illustration, the file's contents are read into a byte slice using the ioutil.ReadFile function. The byte slice is subsequently transformed into a string using the string function. The contents ... Read More
