UOFTBD - Diablo Bot

no tags 

Maybe you've played Diablo? There are three different character classes: Noobs, Suckers, and Pros. Noobs don't know anything about the game. Suckers think they know how to play. Pros know that the goal of the game is to write a script that will farm for valuable items that they can turn around and sell to Suckers on the black market. Obviously Pros would sell to Noobs if they could, but Noobs don't even know how to buy items.

An obvious piece of preqrequisite information for making such a bot is knowing what sorts of items are worth picking up. There are Normal, Magic, Rare, and Set items:

  • Set items always belong to some famous dead person, so they always begin with a word that ends in "'s" (e.g. Andrew's). No other items are special enough to begin this way.
  • Rare items always have names that are two words long.
  • Magic items always have names that are between two and four words long, inclusive. If, and only if, a Magic item has more than two words in its name, then the last two words are "of [something]" (e.g. of Doom).
  • If the first word is "Damaged", the item is a Normal item. Furthermore, any item that could not possibly be Magic, Rare, or Set must also be Normal. No other items are Normal.
  • You may not have played Diablo, but hopefully you still know that a "word" is a maximal substring of non-space characters. Also, letter case is irrelevant.

You have a list of $N$ ($1 \leq N \leq 1000$) item names, and you need to be able to classify these items as accurately as possible. It may not be possible to assign a unique type to each item, but as long as it's not Normal, surely you'll want it. Every item name is a string of no more than 100 characters, containing only alphabetic characters, spaces, and apostrophes. Every name begins and ends with a non-space character.

Input

First line: 1 integer, $N$

Next $N$ lines: The name of the $i$th item, for $i = 1..N$

Output

$N$ lines: The type of the $i$th item (one of "Normal", "Set", "Magic", or "Rare"), or "Not sure, take anyways" (without quotes) if the item's type cannot be determined, but is known not to be Normal, for $i = 1..N$

Example

Input:
7
Somebody's Something of Whatever
stone of jordan
Wirt's Leg
FLAMING TURNIP
Damaged Goods
Sword
Fish shaped volatile organic compounds
Output:
Set
Magic
Set
Not sure, take anyways
Normal
Normal
Normal
 
Explanation of Sample:

The first and third items begin with possessives, so they must be Set items. The second item is three words long, and ends in "of [something]" so it must be Magic. The fourth item could be either Rare or Magic. The fifth item begins with "Damaged" so it's Normal. The last two items don't fit the descriptions of Set, Rare, or Magic, so they must be Normal also.

Finally, stupid mistake costed me few WA. "if, and only if" part was critical for me.

If the first word is "Damaged", the item is a Normal item. Furthermore, any item that could not possibly be Magic, Rare, or Set must also be Normal. No other items are Normal.
@Jacob Plachta
how come sword is normal ?

I'm not a native english speaker. I don't like problems where part of the difficulty is interpreting the statement.
The "if, and only if" part is not clear to me. I got it accepted with the hints in the forum.

RE: "If and only if" is a well-known type of statement in logic, with a single interpretation. But it is easy to not be careful enough.

wow, that is a nice problem... after a naive attempt, took me a week re-reading description and comments... phew, finally found it... :-)

Haijun Deng: 2013-06-13 14:34:33

And what's for "damaged aa of bb"?

RE: All required information can be found in the problem statement - careful reading is required.

Nice question!!
Read carefully..

Chandan Mittal: 2013-06-09 11:13:01

@p-setter
can there be multiple spaces between names or spaces at the beginning/end of string???

RE: As the problem states, not at the start or end. But nothing else is promised.

@numerix: Based on what you asked, you are following exactly the same path of me :)

Federico Lebrón: 2013-06-05 05:42:19

I'm not a native English speaker, and the reason I didn't WA is because I saw that if the code wasn't going to be a challenge, then understanding the solution had to be. So I read slowly, and translated words into formal logic, then formal logic into code.

My suggestion: It's easy to make test cases for this, so take advantage of that. Write test cases you don't know the answer to, and think what the answer should be. Make your code reflect the thought process you had while figuring out the right answer for each test case.
