简而言之,给定一个点列表,返回最接近原点的K,其中K中的顺序无关紧要。我试图通过使用Hoare分区的quickselect变体来解决这个问题,但对于特定的输入,它没有给出正确的答案,我也无法找出原因。Hoare的分区逻辑本身就是从维基百科复制过来的。 点数:[68,97,34,-84,60,100,2,31,-27,-38,-73,-74,-55,-39,62...
If the replacement algorithm malfunctions, FSCQ evicts the first block in the buffer cache. This allows FSCQ to implement replacement algorithms in unverified code while still guaranteeing overall correctness. 缓冲区缓存的设计有一个有趣的方面:它如何实现替换策略。我们希望能够灵活地使用不同的替换算法,...
