In Golang, it is important to know whether a slice is sorted or not, especially when working with algorithms that require sorted data. In this article, we will explore various methods to check if a given slice is sorted or not. Using a Loop to Check if the Slice is Sorted One way to check if a slice is sorted is to use a loop to compare adjacent elements in the slice. If the elements are in ascending order, then the slice is sorted. Here is an example code − Example package main import "fmt" func isSorted(s []int) ... Read More
Presence of a specific character or group of characters in a string is a typical procedure when working with strings. Several methods for determining whether specific characters are present in a Golang string will be covered in this article. Using the strings.Contains() Function Using the built-in strings is the simplest approach to determine whether a character or substring is contained in a Golang string. the contains() function. A boolean value indicating whether the substring was discovered in the string is returned by this function, which requires two arguments: the string to search for and the substring to look for. Here ... Read More
The meaning of image classification is to extract as much information from the image as possible. For example, when you upload an image to Google photos, it extracts information from the image and suggests the location based on that. We can use OpenCV to detect every small information from the image and predict the image. Training and testing models from scratch using JavaScript requires lots of effort, and also, it requires the proper dataset containing the different images. So, in this tutorial, we will use the pre-trained model of ml5.js to classify the image. The ml5.js library contains various pre-trained ... Read More
Channels in Golang are useful for transferring data and coordinating the execution of goroutines. We will go over what channels are, how they operate, and how to use them successfully in Golang in this article. What are Channels? In Golang, channels are a means of data synchronisation and communication between goroutines. A channel primarily functions as a message queue that enables communication between goroutines. Without the requirement for explicit locking or synchronisation, channels offer a secure and effective method of data sharing between goroutines. How Channels Work Channels in Golang are implemented using the chan keyword. Channels can be created ... Read More
In a computer system a deadlock is where two or more processes are unable to proceed because each process is waiting for the other to release a resource that it needs to continue execution. In other words, a deadlock occurs when two or more processes are in a circular wait state, and none of them can release the resources they hold until they receive the resources they are waiting for. Deadlock System Model − The Deadlock System model is a way to describe and analyze systems that may be prone to deadlocks, which occur when two or more processes are ... Read More
Deadlock prevention and avoidance are crucial in operating systems because they help ensure that the system can continue to operate without being stuck in a deadlock. Deadlocks can cause a system-wide halt, leading to loss of data, system downtime, and reduced productivity. Therefore, it is essential to prevent or avoid deadlocks in a computer system to maintain its availability and reliability. Key Areas Covered What is Deadlock? What is Deadlock Prevention? Advantages and Disadvantages of Deadlock Prevention What is Deadlock Avoidance? Advantages and Disadvantages of Deadlock Avoidance Comparison between Deadlock Prevention and Deadlock Avoidance What is Deadlock? Deadlock ... Read More
Deadlock is a complex and potentially detrimental situation that can arise in computer systems where multiple processes are competing for the same shared resources. When two or more processes become deadlocked, it means that each process is holding on to resources that are necessary for the other process(es) to complete their tasks. This can lead to a complete standstill, as none of the processes can move forward without the release of the required resources. Deadlocks can cause severe performance and stability issues in a system, which can ultimately result in system downtime or even failure. Therefore, it is essential to ... Read More
Introduction Contiguous memory allocation is a memory management technique used by operating systems to allocate memory to processes in contiguous blocks. In this technique, a process is allocated a single block of memory that is contiguous or adjacent to each other. This ensures that memory is efficiently utilized, with minimal fragmentation and wasted memory. Contiguous memory allocation is a widely used technique in modern operating systems and has several advantages, including efficient memory utilization, fast access to memory, and simple management. However, it also has some limitations, such as the possibility of external fragmentation, large block requirements, and fixed block ... Read More
Introduction In operating systems, memory allocation refers to the process of assigning memory to different processes or programs running on a computer system. There are two types of memory allocation techniques that operating systems use: contiguous and non-contiguous memory allocation. In contiguous memory allocation, memory is assigned to a process in a contiguous block. In non-contiguous memory allocation, memory is assigned to a process in non-adjacent blocks. Contiguous Memory Allocation Contiguous memory allocation is a technique where the operating system allocates a contiguous block of memory to a process. This memory is allocated in a single, continuous chunk, making it ... Read More
Inversion count is a step counting method by which we can calculate the number of sorting steps taken by a particular array. It is also capable to count the operation time span for an array. But, if we want to sort an array in a reverse manner, the count will be maximum number present in that array. Array: { 5, 4, 3, 2, 1} // for the reverse manner Pairs: {5, 4}, {5, 3} , {3, 2}, {3, 1}, {2, 1}, {4, 3}, {4, 2}, {4, 1}, }, {5, 2}, {5, 1} Output: 10 Array: {1, 2, 3, 4, ... Read More
