lolhaha 的算法的复杂度是 O(N^2).
应该没有比 O(N^2) 更好的算法了，
但是有一个优化可以把算法运行速度大大提升。
根据 lolhaha 的算法，
1.create hash for each word
2.sort the dictionary by word length.
assume the dictionary become
a[0],a[1]......
find the largest k so that hash(a[0])&hash(a[k])==0,
get max=len(a[0])*len(a[k])
find max i in [2,k-1] so that hash(a[1])&hash(a[i])==0,
compare max and len(a[1])*len(a[i])
next step find max j in [3,i-1]....

IPMI 2.0 RAKP Authentication Remote Password Hash Retrieval
More recently, Dan Farmer identified an even bigger issue with the IPMI 2.0
specification. In short, the authentication process for IPMI 2.0 mandates
that the server send a salted SHA1 or MD5 hash of the requested user's
password to the client, prior to the client authenticating. You heard that
right - the BMC will tell you the password hash for any valid user account
you request. This password hash can broken using an offline brutefor... 阅读全帖

"D" for Diamond, "H" for Heart, "S" for spade, "C" for club
Action - (1) Opportunity to act. If a player appears not to realize it's his
turn, the dealer will say "Your action, sir." (2) Bets and raises. "If a
third heart hits the board and there's a lot of action, you have to assume
that somebody has made the flush."
Ante - A small portion of a bet contributed by each player to seed the pot
at the beginning of a poker hand. Most hold'em games

"D" for Diamond, "H" for Heart, "S" for spade, "C" for club
Call - To put into the pot an amount of money equal to the most recent bet
or raise. The term "see" (as in "I'll see that bet") is considered
colloquial.
Calling Station - A weak-passive player who calls a lot, but doesn't raise
or fold much. This is the kind of player you like to have in your game.
Cap - To put in the last raise permitted on a betting round. This is
typically the thi

Equity - Your "rightful" share of a pot. If the pot contains $80, and you
have a 50% chance of winning it, you have $40 equity in the pot. This term
is somewhat fanciful since you will either win $80 or $0, but it gives you
an idea of how much you can "expect" to win.
Expectation - (1) The amount you expect to gain on average if you make a
certain play. For instance, suppose you put $

Jackpot - A special bonus paid to the loser of a hand if he gets a very good
hand beaten. In hold'em, the "loser" must typically get aces full or better
beaten. In some of the large southern California card clubs, jackpots have
gotten over $50,000. Of course, the jackpot is funded with money removed
from the game as part of the rake.
Kicker - An unpaired card used to determine the bet

"D" for Diamond, "H" for Heart, "S" for spade, "C" for club
Pay Off - To call a bet when the bettor is representing a hand that you can'
t beat, but the pot is sufficiently large to justify a call anyway. Example:
"He played it exactly like he made the flush, but I had top set so I paid
him off."
Play the Board - To show down a hand in hold'em when your cards don't make a
hand any better than is shown on the board. For instance, if you have 22

Scare Card - A card that may well turn the best hand into trash. If you have
TC -8C and the flop comes QD-JD-9S , you almost assuredly have the best
hand. However, a turn card of TD would be very scary because it would
almost guar-antee that you are now beaten.
Second Pair - A pair with the second highest card on the flop. If you have
AS -TS, and the flop comes KD-TH-6C , you have fl

Table Stakes - A rule in a poker game meaning that a player may not go into
his pocket for money during a hand. He may only invest the amount of money
in front of him into the current pot. If he runs out of chips during the
hand, a side pot is created in which he has no interest. All casino poker is
played table stakes. The definition sometimes also includes the rule that a
