, and the modulus (the amount of "overflow") is 12. Now we move the hour hand counterclockwise from 4 to 2, and move clockwise 10 to get the same result. The arithmetic formula is 4-2 and 4+10, at a glance 4-2 is obviously not equal to 4+10, then why the two results on the clock is the same?That's "modulo" in mischief. When the result of the operation exceeds the counting range, the modulo operation is performed, and the 4+10=14>12,12 is 2=4+ (-2) after the modulo is obtained. At this point you

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

The work of Miller and Rabin has taken a revolutionary step in the Fermat test and established the legendary Miller-Rabin algorithm. The new test is based on the following theorem: If P is a prime number, X is a positive integer smaller than P, and x ^ 2

Because to get (x, y-1) These, but also recursive processing, will be GG.Then find the rule is C (x + y, y)-C (x + y, y-1)Cannot nothing more yy. Try to match the relationship between X and Y.Generally must be related to these two numbers, and 2 * x these few relationships.#include #include#includ

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.
