For example, lets find the gcd of 14 and 24. 14 has divisor set {1;2;7;14}. 24 has divisor set {1;2;3;4;6;8;12;24}. The largest number in both divisor sets is 2. So 2 is the gcd of 14 and 24. Alternatively, you could calculate the gcd by comparing the prime factorizat...

最大公约数是指能够整除多个整数的最大正整数(这里面多个整数不能都为0)例如6和4的最大公约数就是2,13和3的最大公约数是1。 算法实现 平时用的时候如果是C++,那么std库里面就已经有这个函数了,直接调用就行。具体可以看std::gcd的用法。比较常见的实现方式是: ...
int gcd(int a,int b) { if(!a)return b;//a=0 if(!b)return a;//b=0 int shift;//a,b二进制下末尾0的个数 for(shift=0;~(a|b)&1;++shift)a>>=1,b>>=1;//把两个数末尾的shift个0都去掉 while(~a&1)a>>=1;//现在两个数至少有一个奇数,2一定不是公约数 //现在a一定是奇数...
GCD是苹果在OS X Snow Leopard跟iOS4后引入的一个技术,利用GCD,我们可以将多线程代码编写的很优雅。在使用GCD前,我们可以简章回顾下传统的多线程技术。1 int main() {2 id o = [[MyObject alloc] init];3 [o execBlock];
重复步骤2至4,直至B为0。此时A即为所求的最大公因数GCD(A, B)。 算法终止条件:当余数R为0时,算法停止。 算法解释:欧几里得算法基于这样一个事实:对于整数A和B(A > B),若R是A除以B的余数,则GCD(A, B) = GCD(B, R)。这是因为任何同时能整除A和B的数,也必然能整除B和R。通过不断将大数替换为余...
