Suppose you are inserting newspaper.
You go through the trie (an up to 26 branching tree), you will stop at news,
and check the paper from the root of trip. On average the complexity is n.
In the worst case, suppose, all n, ne, new, news, newsp, newspa, newspap, ne
wspape, are all on your trie, you will have to look through all ewspaper, ws
paper, spaper, paper, aper, per, er, r, each look up takes n time and you ha

发帖数: 360 | 5 No GC redemption but UA mileage is probably one of the easiest mileages to extend. Here is a
summary sorted from my most recommended to least.
1. Link your UA account with Grocery account (Safeway, Vons etc). Get
125 miles for each $250 spent. Slow but worry-free, no cost. Too bad this
program will end on March 1, 2010.
2. Subscribe for newspaper. Especially Sunday only newspaper subscription
, which comes with loads of coupons. Dollar-value wise the best use of
mileages.
