Word Counting

Problem code: WCOUNT

All Submissions

All submissions for this problem are available.

Chef has decided to retire and settle near a peaceful beach. He had always been interested in literature & linguistics. Now when he has leisure time, he plans to read a lot of novels and understand structure of languages. Today he has decided to learn a difficult language called Smeagolese. Smeagolese is an exotic language whose alphabet is lowercase and uppercase roman letters. Also every word on this alphabet is a meaningful word in Smeagolese. Chef, we all know is a fierce learner - he has given himself a tough exercise. He has taken a word and wants to determine all possible anagrams of the word which mean something in Smeagolese. Can you help him ?

Input

Input begins with a single integer T, denoting the number of test cases. After that T lines follow each containing a single string S - the word chef has chosen. You can assume that 1 <= T <= 500 and 1 <= |S| <= 500. You can also assume that no character repeats more than 10 times in the string.

Output

Output one line per test case - the number of different words that are anagrams of the word that chef has chosen. As answer can get huge, print it modulo 10^9 + 7

Example

Input:
4
ab
aa
aA
AAbaz

Output:
2
1
2
60

Description: In first case "ab" & "ba" are two different words. In third case, note that A & a are different alphabets and hence "Aa" & "aA" are different words.

why i am keep getting RE. my prog is working correctly on my m/c..

Same here ... SIGFPE is RE

me too... it's giving wrong

elmagnifico @ 1 Feb 2012 08:12 PM

me too... it's giving wrong answer but on my pc i tried almost 50 different words... All gave correct answers....

Please read our FAQ:

@darkdiver. There are 26

anton_adm @ 2 Feb 2012 01:27 AM

@darkdiver. There are 26 Roman letters. So the upper bound from here is 520 and 500 is independent bound.

Does modulo 10^9 +7 mean (x

debjitbis08 @ 2 Feb 2012 01:58 AM

Does modulo 10^9 +7 mean (x modulo (10^9 +7)) or (x modulo (10^9) + 7)?

modulo 10^9 +7 will mean (x

wrongnumber @ 2 Feb 2012 02:10 AM

modulo 10^9 +7 will mean (x mod 1000000007)

can you provide some test

richi18007 @ 2 Feb 2012 03:26 AM

can you provide some test cases , it is WA and I have tried a lot of test cases and my code gives correct answer on them

i think runtime errors are

juahn31 @ 2 Feb 2012 05:38 AM

i think runtime errors are due to so big inputs, i also get run time error

any sorts of word are always

yosuke_fujii @ 2 Feb 2012 06:39 AM

any sorts of word are always meaningful word of Smeagolese, aren't them? i write code which can always return correct answer in this understanding, but i received WA... (of course i pay attention to same letter and correct all of example case :( )

@debjitbis08 : It means : x

nikhil_adm @ 2 Feb 2012 10:10 AM

@debjitbis08 : It means : x modulo (10^9 + 7)

@yosuke_fuji : Yes, all words

nikhil_adm @ 2 Feb 2012 10:11 AM

@yosuke_fuji : Yes, all words are always meaningful in Smeagolese. You'd have to find out the bug in your algorithm/program yourself, we can't help you there.

The input does not contain

mvivek241 @ 2 Feb 2012 11:03 AM

The input does not contain spaces, right? And can you provide 1 or 2 larger inputs and their expected outputs, i want to check if my program works.

String will contain only

anshuavi @ 2 Feb 2012 05:55 PM

String will contain only alphabets and no other special characters,right?

i cannot submit my

vamsi2708 @ 2 Feb 2012 05:57 PM

@nikhil_adm you should give

crazycoder_sns @ 4 Feb 2012 12:21 AM

@nikhil_adm you should give some test cases in each problem for better understanding.....:-p

The last sample test case

calc_saransh @ 4 Feb 2012 03:57 AM

The last sample test case clearly defines the problem if the problem statement was even a little unclear.

cupidvogel @ 6 Feb 2012 02:25 PM

I don't understand, I have checked my code with words 600 characters long, and that too with huge number of occurrences of two or three particular letters so that I can test it with large numbers (factorials), and there I am getting instantaneous results. How come here it is showing time limit exceeded?

Come on, I tried my code with the most stringent string, that is a to z and A to Z each repeated 10 times, and I got the answer instantly. How come here it is showing time limit exceeded?

@admin: exactly sample prblm

savvy_fedex @ 6 Feb 2012 09:53 PM

max length of string is <=500...?? i read in comments......someone saying 520..??

I'm getting TLE. I looked up

irajvardhan @ 8 Feb 2012 11:42 PM

I'm getting TLE. I looked up the FAQ and as suggested used the "time ./out.txt" command. I got three different time results...'real' 'user' and 'system'. Which among these should be below the given time constraint?

this is so pathetic.i am

@pratishgupta91::Be CareFul

ritesh_gupta @ 9 Feb 2012 01:46 PM

@pratishgupta91::Be CareFul with Overflow.Try to Handle the Datatype overflow,properly...I saw the judge (exclusively in this problem)gave wrong answer ,even if the program encounters datatype overflow,infact the judge should have actually display Runtime error in that case..

still WA....took care of

phoenix_shaan @ 9 Feb 2012 08:47 PM

still WA....took care of overflow though

@admin submitted the problem

rdaxxx @ 9 Feb 2012 11:05 PM

@admin submitted the problem at least 10 times and still wrong answer although checked by me on different-2 test condtion all are correct , please any one give me a better test condition to test on , plz help , any one ????????/

i submitted my solution, it

codetantra @ 11 Feb 2012 12:35 AM

i submitted my solution, it works, but on my PC it takes 5.7 secs (worst case scenario) and on codechef it takes 13.6 secs. is this expected?
