This function is a good one I accidentally saw. It is awesome and I like it.
Is used to find the minimum public approx.
A simple description is that gcd (a, B) indicates the maximum public factor of non-negative integers A and B, so: gcd (a, B) =

Question:
For a number N, obtain the maximum Q so that n = a ^ Q, where a, Q, and n are all 32-bit integers. (Multiple groups of data)
Analysis: As long as N is decomposed, gcd of all prime

Algorithm Summary-Euclidean AlgorithmEuclidean algorithms 1. Euclidean algorithms the Euclidean algorithm is also known as the moving phase division. It is used to calculate the maximum approximate numbers of two positive integers a and B. The

1. The method of Euclidean algorithmThe greatest common divisor of two integers is obtained by using the method of dividing the two. Note GCD (A, A, b) is a greatest common divisor of two numbers a and a. The theoretical basis for the Euclidean

Main topic:A password box, the number is 0~n-1, which has a number of passwords, the characteristics of the password: if x is the password, y is the password, (x can be equal to Y) then (x+y)%n is also the password.Give a n (In 0~n-1, how many
