A mason prime number is a positive integer, such as a 2^p-1, in which the exponent P is a prime and is often recorded as an MP. If the MP is a prime number, it is called a mason prime. p=2,3,5,7, MP is prime, but m11=2047=23x89 is not prime The mason number may be prime or composite, so how to judge the Mason number is

Myth #12: The number of files in tempdb is consistent with the number of CPUs required Error Alas, this myth is a cliché because it is Microsoft's "official" advice, and there are a lot of posts sticking to that view. But the confusing thing is that the SQL Cat team's recommendation is 1:1, but it comes from the principle of extension rather than a general rule. Because of the large

Description In mathematics, a squarefree number is one which are divisible by no perfect squares, except 1. For example, Square-free but, as it is divisible by 9 = 3^2. Now you are need to determine whether an integer is Squarefree or. Input The ' The ' contains an integer T indicating the number of test cases. For each test case, the there is a single line contains an integer N. Technical Specification 1

How to identify the number of physical CPUs, a few cores, is hyper-threading or multi-core Judge the basis: 1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores. English version: 1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any CPU with the same physical ID ar

Given a function that randomly generates integers 1 through n, a function (M > N) that can randomly generate integers 1 to M is written. Set n = 5, M = 7The key is to have the same probability of generating 1 to 7 of the number. Call N-time given function, generate n 1 to 5, select the maximum number of positions until the last one is left. Such as:Initial 7 numbers [1, 2, 3, 4, 5, 6, 7].(1) 7 random number
