The ability to generate random numbers or alphanumeric strings comes in handy in many situations. You can use it to spawn enemies or food at different locations in the game. You can also use it to suggest random passwords to users or create filenames to save files. I wrote a tutorial on how to generate random alphanumeric strings in PHP. I said at the beginning of this post that few events are truly random, and the same applies to random number or string generation. In this tutorial, I'll show you how to generate a pseudo-random alphanumeric string in JavaScript. Generating Random Numbers in JavaScript Let’s start by generating random numbers. The first method that comes to mind is Math.random(), which returns a float

The difference between random and pseudo-random is predictability, reproducibility, uniformity and security. Detailed introduction: 1. Predictability. Random numbers cannot be predicted. Even if the past results are known, future results cannot be accurately predicted. Pseudo-random numbers can be predicted because they are generated by algorithms. As long as you know the algorithm and seed, you can regenerate the same sequence or sequence; 2. Reproducibility, random numbers are not reproducible, and the results generated each time are independent, while pseudo-random numbers are reproducible. Yes, just use the same algorithm and seeds etc.

Python is a popular programming language widely used in data analysis, machine learning, web development and other fields. In Python, the random module provides a random.randint() function for generating random integers. This article explains how to use the random.randint() function to generate random integers and provides some code examples. First, we need to import the random module: importrandom Next, we can call rando

Here we will see how to print numbers in the correct order using different threads. Here we will create n threads and then synchronize them. The idea is that the first thread will print 1, then the second thread will print 2, and so on. When one thread tries to print, it locks the resource so other threads cannot use that part. Example #include<pthread.h>#include<stdio.h>#include<stdlib.h>#include<unistd.h>pthread_mutex_tmutex=PTHREAD_MUTEX_I

In this article, we will learn what a fluctuating number is and introduce our method of checking whether a given number is a fluctuating number, using a Boolean function to check for fluctuating numbers. Problem Statement We will be given a number and our task is to check if the given number is fluctuating. Let's first understand a fluctuating number; a fluctuating number is a number that consists of only two types of numbers, with every other number being the same. We can say that a fluctuating number is of the form "PQPQPQ" where P and Q are two different numbers in the number system. The first and second digits of a fluctuating number can never be the same, that is, 11111 is not a fluctuating number. We usually regard non-trivial fluctuating numbers as just fluctuating numbers, which means that the fluctuating numbers need to be composed of at least 3 digits

Python is a flexible and efficient programming language that provides a wide range of low-level functions and libraries to improve complex coding tasks. One of the tasks is to perform weighted irregular decision making, a measurable strategy where everything has a predefined probability of being picked. Unlike simple random selection, where each item has an equal chance of being selected, weighted random selection allows us to specify a probability of each item being selected, which may vary. This article aims to provide a comprehensive understanding of how to obtain weighted random selection in Python. Syntax The main method in Python that facilitates weighted random choices is random.choices(). This is its basic syntax: random.choices(popula

In the world of programming, the ability to generate random values is often crucial. Whether you are developing a game, simulation, statistical model, or simply need to introduce variability into your program, having a reliable and efficient way to generate random numbers is crucial. This is where the PythonRandom module comes in. The PythonRandom module provides a set of functions for generating random values, making it easy to introduce randomness into Python programs. From generating random numbers within a specific range to shuffling lists, simulating random events, and even generating random passwords, the Random module provides a wide range of functionality. In this blog post, we will explore the PythonRandom module in detail. We will learn how to generate random numbers, perform

CSS3 Selector Priority Order In CSS, the priority of a selector determines which rule will be applied to an element. When multiple rules have the same priority, they are applied in the order in which they appear. For rules with different priorities, CSS uses a specific algorithm to determine which rule is ultimately applied. Below we will introduce the order of selector priorities in CSS3 and provide specific code examples. In CSS, the priority of a selector is determined by the following factors: Inline style sheets (Inlinestyles): Inline
