inverse factorial function

Don't be intimidated by factorial. DescriptionFactorial (factorial) is a very interesting function, but a lot of people are afraid of it, let's look at two factorial-related problems:Question 1. Given an integer n, then the factorial n of n! How

New students in computer science often find it difficult to understand the concept of recursive programming. Recursive thinking is difficult because it is very much like cyclic reasoning ( circular reasoning ). It is also not an intuitive process;

Since it is functional programming, it is naturally unavoidable to know more about the function:Methods are not equal to functions (function)The method is not a function but can be converted into a function, can be converted by hand or automatically

Creation of the object:1.new constructor var person = new Object (); Person.name = "Qi";2. Object literal (preferred) var person={name: "Qi", age:22}///can also "name": "Qi" Here the name will be automatically converted to a stringor Var person={};

 AbsABS (number): Returns the absolute value of the specified digit. An absolute value is a numeric value that has no sign.Number: Any real number that requires an absolute value.Example:ABS (-1.5) equals 1.5.ABS (0) equals 0.ABS (2.5) equals

The last article gave the recursive completion of the string inverse of the code, but did not analyze its specific algorithm, today, as the ' ABCDE ' string recursive flip diagram to share with you (the picture is rotten, concrete ideas are still

Lucas theoremA, B is a non-negative integer and P is a prime number. AB is written in P-system: a=a[n]a[n-1]...a[0],b=b[n]b[n-1]...b[0].The combined number C (A, B) and C (A[n],b[n]) *c (a[n-1],b[n-1]) *...*c (a[0],b[0]) MODP the samenamely: Lucas
