大整数算法之gcd(最大公约数) 欧几里德算法(Euclid)阐述了一种gcd算法。gcd(greatest common divisor),简言之,我们想求gcd(x,y),假设(x>y),如果存在下式:x = q*y + r,那么则有gcd(x,y) = gcd(y,r) ,其实上式也称为gcd递归定理,即gcd(a,b) = gcd (b,a mod b)。
However, there're something called __gcd() If you want the GCD of a and b, you can write the following code: intgcd(inta,intb){if(b==0)returna;elsereturngcd(b,a%b);} And for LCM: intlcm(inta,intb){returna*b/gcd(a,b);} ...
Execute code concurrently on multicore hardware by submitting work to dispatch queues managed by the system.通过向系统管理的 dispatch queues 提交工作来在多核硬件上并发执行代码。 GCD,是 iOS 中多线程编程使用最多也是最方便的解决方案。 使用GCD 有如下好处: GCD 会自动使用更多的 CPU 内核; GCD 自动管...
