N But it's definitely not one and in fact it wasn't N in the case of Selection Sort because remember the algorithm we implemented on stage last week had me going back and forth across the stage selecting on iteration, the smallest person I can find, the smallest number and then putting them into place.

但在选择排序中，肯定不会是1，也不是,注意，上周我们在这儿,实现的算法中，反复地,迭代进行选择，选出最小的数,然后将其放在合适的位置。

They found that detecting and treating many early-stage breast cancers reduced the number of late-stage cancers and deaths only slightly, prompting them to conclude that much of the treatment was unnecessary in some cases because the cancers wouldn't have progressed, and in some cases because they were fatal despite being treated early.
