1.开放式问题,有些网站每天只允许有限次访问,怎么抓取网页使得索引尽量全面和新鲜
??
2.在C++文件中只declare class A, 但不以任何方式define class A, 是做什么用
3. Estimate the time cost of transfering 1M of data from one memory stick to
another.
- when the data in memory is sequentially stored; - when the
data in memory is stored in blocks; - does the bus width matter
here?
4.How to transform a unbalanced tree into balanced tree?
第2个题我想的是保留A的名字,以后再定义
第四个题我想的是先算每个节点的blance factor然后再调整,具体怎么调整就不知道了。
第四个题还想到一个办法是转成双链表,然后再转balanced tre
