Article Introduction：If you are using an operating system, you must count the number of files available in a directory as it provides a brief overview of the contents. It allows you to limit storage space and get details of unnecessarily large files. Additionally, as a Bash script user, you can count the number of files to automate specific tasks and limit the number of them. However, many beginners want to know how to check the number of files. Therefore, we provide several commands on the blog that can help them quickly count the number of files available in a directory. How to count the number of files in a directory on Linux Let us divide this guide into multiple sections, in which we will explain the different commands for counting the number of files in Linux. 1.Wc command you can use "wc"

Article Introduction：PHP and GMP Tutorial: How to Compute Modular Exponentiation of Large Numbers In computer science, modular exponentiation is a common operation, especially in the fields of cryptography and number theory. When numbers are very large, performing exponentiation and modular operations directly may cause memory overflow or exceed the computer's processing capabilities. To solve this problem, PHP provides the GMP extension to handle large number operations, which can also be used to calculate exponentiation and modular operations. This tutorial will show you how to use PHP's GMP extension to calculate modular exponentiation of large numbers. We will divide it into the following steps

Article Introduction：PHP and GMP tutorial: How to calculate the Euler function value of large numbers. The Euler function is an important concept in number theory. It is used to calculate the number of numbers that are relatively prime to n among positive integers less than or equal to n. When calculating decimals, we can directly use the definition of Euler's function to calculate, but when encountering large numbers, direct calculation may be very time-consuming. So how to use PHP and GMP libraries to calculate the Euler function value of large numbers? This tutorial will show you how to use PHP and the GMP library to calculate the Euler function value of large numbers. First, we need to understand
