go ignores the Gopath and vendor folders, depending only on the go.mod download.
Auto or not set, the GO command enables or disables module support based on the current directory. Module support is enabled only if the current directory is outside of GOPATH/SRC and itself contains a Go.mod file or is located in a directory that contains go.mod files.
Defining a Module
Who doesn't know how to use it when it starts? But go has provided me with a tool that can be entered in the console:
go h
People See people love a^b
Problem Description An integer representing the last three digits of the a^b. Description: The meaning of A^b is "A's B-square"
Input data contains multiple test instances, one row per instance, consisting of two positive integers a and B (1B=0, it indicates the end of the input data and does not handle it.
Output for each test instance, print the last three bits of the a^b that represent the integers, one row for each output.

2 positive Powers-2, 4, 8, 16, 32, 64, 128, 256, ...-at the end of the numbers follow an obvious rule: 2, 4, 8, 6, 2, 4, 8, 6, .... These 4 numbers are always going to loop. In addition to the last number there is a loop-actually the final m bit-a power of 2 starting at 2m. For example, there is a loop of length 20 for the last two digits starting at 04, and a loop of length 100 for the last 3 digits starting from 008.In this article, I will show you why there are these loops, how long they are,

Euclidean algorithm: A fast algorithm for the greatest common divisor of two integers. That is what is commonly referred to as the "Euclidean method". Given two integers a, b. Euclid can find A, B greatest common divisor in the complexity of log (max (|a|, |b|)) in the worst possible degree. The computational method of time complexity is also very interesting, see "Introduction to Algorithms".Prove the correctness of Euclid's algorithm:A can be expressed as A = kb + R, and r = a
operational rules for modulesArithmetic RulesThe modulo operation is somewhat similar to the basic arithmetic, but with the exception of division. The rules are as follows: (A + b)% P = (a% p + b% p)% p (1) (A-a)% P = (a% p-b p)% P (2) (A * b)% P = (a% p * b% p)% P (3) (A^B) % P = ((a% p) ^b)% P (4) Binding Law: ((a+b)% p + c)% P = (A + (b+c)% p)% P (5) ((a*b)% P * C)% P = (A * b*c)% P (6)//(A%p*b )%p= (A*B)%p Exchange Law: (A + b)% P = (b+a)% P (7) (A * b)% P = (b * A)% P (8) Distributive Law:

DescriptionToday's math class, crash children learn least common multiple (Least Common multiple). For two positive integers a and B,LCM (A, b) represent the smallest positive integers that can be divisible by A and b at the same time. For example, the LCM (6, 8) = 24. Back home, crash still thinking about class school, in order to study least common multiple, he drew a n*m form. A number is written in each lattice, where the lattice in column J of Row I is written in the LCM (i, J). A 4*5 table
