Rand random number-guessing number game implementation
Game Requirements: The computer automatically generates random numbers from 1 to 100 The player guesses the number. During the process of guessing the number, feedback is given as to whether the number is too big or too small according to the size of the guessed number. Until the correct answer is guessed, the game ends. […]

C++ binary algorithm: random numbers in blacklist
Involving knowledge points binary search Title Given an integer n and a non-duplicate blacklist integer array blacklist . Design an algorithm to select an integer that is not included in the blacklist from any integer in the range [0, n – 1]. Any integer in the above range that is not in the blacklist should […]

The random module in Python, the magical world of randomness
Randomness plays a crucial role in computer programming and data science. The random module in Python provides a wealth of tools and functions to help us generate random numbers, operate random sequences, and simulate random events. In this article, we will share the random module, understand its basic usage, functions and application areas, and provide […]
