1 给任意一个double,如何构建一个hash function to get a key?
2 给一个N,几个质数,打印这些质数的倍数,我给了给所有的N构建flag的solution,
然后他说如果range很大呢,比如1b? space是一个问题。
3 实现vector的resize问题,请问这个问题的trick是什么?
4 prefix tree, what if the words are very long, total number of words are
small, and the characters are more than 26. How to optimize?
