更多“利用素因数分解计算gcd(36, 48)和lcm(36,48)。”相关的问题 第1题 试编写一个算法,求解最大公因数问题:在求两个正整数m和n的最大公因数时常常使用辗转相除法,反 复计算直到余数为零为止。其递归定义为: 例如,求72和40的最大公因数,即计算GCD(724,344): GCD(724,344)=GCD(344,724%344)=GCD...

// 同步执行任务创建方法dispatch_sync(queue,^{// 这里放同步执行任务代码});// 异步执行任务创建方法dispatch_async(queue,^{// 这里放异步执行任务代码}); 虽然使用 GCD 只需两步,但是既然我们有两种队列(串行队列/并发队列),两种任务执行方式(同步执行/异步执行),那么我们就有了四种不同的组合方式。这四种...
