Course Introduction:PHP and GMP Tutorial: How to Calculate the Total Permutation of Large Numbers Introduction In computer science, the total permutation refers to all possible arrangements of a set of elements. For small-scale element combinations, we can use recursion or iteration to implement the full permutation algorithm. However, when dealing with large numbers, such as numbers above 100 digits, traditional algorithms are insufficient. In this tutorial, we will explain how to use PHP and the GMP extension to calculate the total permutation of large numbers. Introduction to GMP extensionGMP (GNUMultiplePr
