if the portuegese verb doesn't end with 'r'
then print the unknown conjugation right away.

Hello sumankar, maybe it'll be more helpful if you post your code here so it can be evaluated. Or at least you can tell where your confusion lies. Besides I think (only a thought, not yet a conclusion) that the judging for this prob is buggy (Note that this is merely an assumption). I'll post later my AC code and my 'should be AC' code.
There are 3 things one need to be successful : motivation, ability and chance. And if you're a believer, make it four : God's will.

10197 - Runtime Error

Post by mooseelkdog » Fri Dec 05, 2003 4:01 am

I compile and run this fine off my computer, using g++, why does UVA give me a runtime error for this?

Code: Select all

Thought I just might drop this one. A word can consist of only a valid suffix, ie length of the root of the word is 0. I assumed otherwise, so got a bit of nasty testing.

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.

10197 WA

Post by Guest » Mon Jul 12, 2004 6:32 am

Hi Sohel,

I'm also getting WA for this problem. You've posted "I consdered two lettered portugese words as having no conjugation. But in this program this is not so. ", could you please explain what do you mean by this?

I thought that every word in the input should have two letter suffix at the end. So two letter words can be the suffixes only. But still I'm getting WA. So please help me.

It would be better if you'd provide some critical inputs. That way it would be easier for me to find my mistake.

Thank you. :)

test cases

Post by sohel » Mon Jul 12, 2004 1:02 pm

I thought two lettered words ( suppose ir ) had no conjugation. But I was wrong.

Here is some test cases you can try :

falar talk
ir sohel
or turjo
i cry
sir pray
tirr con
abcdef do

falar (to talk)
eu falo
tu falas
ele/ela fala

A B-i-G thanks to Sohel :wink: for the help, (and so fast too :D )
I've got accepted.

My mistake was that for 2 letter words i was printing the word as well, where i was supposed to print the "o,es,e,imos" etc only.

Thanks again!

Hello, I'm having trouble with this same problem. I'll use this thread to avoid creating a new one. The code is getting WA.

My algorithm and some implementation info:

Code: Select all

while loop fetching two strings with scanf until eof
  show the portuguese verb and the english correspondent
  get last char and the tv char into char variables
  switch the tv var
    case 'a', conj = 1
    case 'e', conj = 2
    case 'i', conj = 3
    default, conj = 0
  get the root to a string variable
  if last char is not 'r', conj = 0
  if conj = 0
    show unknow
  else if conj = 1 or conj = 2
    show 1st or 2nd conjugations
  else if conj = 3
    show 3rd conjugation
Any suggestions?

Dear JackBauer,

What is your output for this case ?

Code: Select all

partir go away
my ac code gives this output

Code: Select all

partir (to go away)
eu        parto
tu        partes
ele/ela   parte

indeed that breaks my code since I was assuming the english verb part would be a single word.

Fixed that, still gives WA.

to JackBauer,

I used to scanf("%s") the Portugese part then scanf("%c") to get the spaces and then gets() to take the english part. Your algo seems OK to me. Chek the spellings carefully, very carefully. You know what sort of problem is this one. :)

10197 PE

Post by acMustaine » Mon Jun 06, 2005 4:43 am

I post my code and i get PE. I have 2 ideas about:

a) I dont know if the words (english or portuguese) can have spaces. I supposse that they won't have.
b) I suppossed that i get PE because i always in each case print two '\n' at the end of the output.

If you know something about please write.

Before AC of this problem, I had 2 PE's.

a) I read the line with two words, I found first space (ASCII 32) and I supposed, that before this space is portuguese word and behind this space is english word. Also - portuguese word cannot have space (if it not so, I will have WA), english word may have spaces.

b) Empty line should be behind each case except the last case. Or - empty line should be before each case except first case. Also, at the end of the output shouldn't be blank line.

I had PE because I printed too many blanks between conjugators and verbs. I printed the verbs in 12th column (correct is 11th column).

I have no more idea for having PE.

Please sorry for my bad english.
