問題文
Two habits of the turned-back rows are checked. First, when the same key turns up twice on the way into a marked-up write target, of two places a row could be put, one is where such a row is put and the other is where it is never put. Second, when the work is split several ways, each split gets a file of its own for the rows it turns back, and of two splits only one has a number put into that file's name. Which pairing fits?
