The most important part of a GSM network is so calledBase transceiver station(BTS). These transceivers form the areas calledCells(This term gave the name to the cellular phone) and every phone connects to the BTS with the strongest signal (in a little simplified view ). of course, btses need some attention and technicians need to check their function periodically. The technicians faced a very interesting problem recently. given a set of btses to visit, they needed to find the shortest path to vi

A headache program; Calculate a factorial of less than 100. This is my program, which can calculate a factorial of less than 10000: 1 #include Although the results are correct, I still couldn't do it for a long time by referring to other people's algorithms. I finally breathed a sigh of relief. It wasn't until I saw this program that my code was a bunch of shit. Excellent code: 1 /*Small factorials*/ 2

Problem description: Calculate the factorial of an integer N, 0 For example, if n is 50, the result is 30414093201713378043612608166064768844377641568960512000000000000. Idea: Starting from the factorial definition, n! = N * (n-1) * (n-2) *... * 2*1. Because N is large, basic data types cannot be stored. However, we can use an integer array to store results (including intermediate results). Each element of

Two Methods for C ++ to calculate factorial This article mainly introduces two methods to calculate factorial in C ++. If you need it, refer 1. Use static local variable static The static local variable does not disappear after the function call and retains the original value, that is, the storage units it occupies are not released. During the next function call, this variable retains the value at the end

What if we want to accurately calculate a large number, such as a 256 factorial (with more than 500 digits?You will say, it's easy to do. Since JDK 1.1, Java does not provide {Tagshow (Event)} "> JAVA. Math. biginteger? Yes. Using biginteger can solve the problem. However, without the class given by Sun, we only rely on the most basic types of Java. Is there a way to perform computation? The answer is: yes. What else should I do before biginteger.One

Tags: N, last n, factorial, last non-0 The problem is to ask about n! The last digit of is not 0, such as 3! = 6, the last non-0 digit is 6, 5! = 120, the last non-0 bit is 2. How can we quickly find the last non-0 bit? The simplest idea is to find n first! And then obtain the last non-zero digit of the result. when N is relatively small, it can be tolerated, but when n reaches a certain scale, the time and space will not be too good. some tips ar

High-precision operations are easy to implement in Java, just like A + b problem, because Java provides the appropriate class libraries and APIs, but there are no ready-made classes and APIs for you to call in C + +. In the spirit of "hands-on, clothed" coder, or on their own. Let's take a look at how to make the factorial of a large number using C + +./**from: "Algorithmic Competition Primer"-Rujia *author:yq_beyond *date:2015.03.29*//*High-precision
