The question defines a number called a half prime number: As long as a number can be divided into two prime numbers, this number is a half prime number.Prime

A natural number greater than 1, except 1 and itself, cannot be divisible by other natural numbers (prime numbers) (2, 3, 5, 7, etc.), in other words, the number has no other factor other than 1 and itself.First, let's take the first traditional judgment:def handlernum (num):# Prime

Question link: Ah, haha, click me Question: two numbers are given, which are obtained by the decomposition theorem. Each number can be divided into the product of several prime factors, in this way, the point can be expressed in an n-dimensional coordinate system... For example, 50 and 24 Because 24 = 2 ^ 3*3 ^ 1*5 ^ 0 and 50 = 2 ^ 1*3 ^ 0*5 ^ 2, the two points can be in a 3-dimensional coordinate system. i
