Canadian Computing Competition: 2011 Stage 1, Senior #1

You would like to do some experiments in natural language processing. Natural language processing (NLP) involves using machines to recognize human languages.

Your first idea is to write a program that can distinguish English text from French text.

After some analysis, you have concluded that a very reasonable way of distinguishing these two languages is to compare the occurrences of the letters t and T to the occurrences of the letters s and S. Specifically:

if the given text has more t and T characters than s and S characters, we will say that it is (probably) English text;
if the given text has more s and S characters than t and T characters, we will say that it is (probably) French text;
if the number of t and T characters is the same as the number of s and S characters, we will say that it is (probably) French text.

Input Specification

The input will contain the number $N$ ~N~ $(0 < N < 10\,000)$ ~(0 < N < 10\,000)~ followed by $N$ ~N~ lines of text, where each line has at least one character and no more than $100$ ~100~ characters.

Output Specification

Your output will be one line. This line will either consist of the word English (indicating the text is probably English) or French (indicating the text is probably French).

Sample Input 1

3
The red cat sat on the mat.
Why are you so sad cat?
Don't ask that.

Output for Sample Input 1

English

Sample Input 2

3
Lorsque j'avais six ans j'ai vu, une fois,
une magnifique image,
dans un livre

Output for Sample Input 2

French

(Note: Sample Input 2 is the first sentence of Le Petit Prince by Antoine de Saint-Exupéry.)

Sample Input 3

4
Si je discernais ta voix encore
Connaissant ce coeur qui doute,
Tu me dirais de tirer un trait
Quoi que partir me coute.

Output for Sample Input 3

English

(Note: Sample Input 3 is added by DMOJ from Le Fantôme de l'Opéra.)

The question states:

if the number of t and T characters is the same as the number of s and S characters, we will say that it is (probably) French text.

However, in test case 3, I output the number of t's and s's and apparently there is 0 of each of them. But the solution is "English". I had to hardcode it to solve the problem. Please do something about it.

Edit: or was there a problem with my code?

You are forgetting that C/C++ style input stops with all whitespace characters, so doing this:

string str; cin >> str;

will read but a single word from the first line of the input. What you should be doing is reading the entire line:

string str; getline(cin, str);

I already AC'd by hard-coding, but why does this solution using getline WA case 3?

You should insert cin.ignore() between lines 9 and 10 to ignore the new line character which has not been read by cin >> N.

Worked, thank you!

Can anyone tell me what's wrong with my test case 3?

Your code is doing some funky stuff, Also, as I told you again, please join the dmoj slack

Your submission is testing each line for its language individually and then choosing the language that appeared most often in all the lines. But that's not what the question asks for.

I'm not sure what's wrong with my code, I failed test case 3. Can someone help?

I don't see anything wrong with your actual code. I believe that the problem is that right after you have scanner.nextInt(), when you use scanner.nextLine() it actually reads the same line of the integer, meaning it would read nothing. So just use an extra scanner.nextLine() in between your reading of "a" and your lines, and don't use it. That hopefully should fix the problem.

It worked thank you so much!

I speak french, and t actually works at guessing the language! Cool problem!

I think that my submission is totaly true but i got just 40, any help or idea about what's going wrong please?!

ZippIE commented on Dec. 21, 2017, 12:09 p.m.

if the given text has more t and T characters than s and S characters

Your program only counts then individually

AmineHamoura commented on Dec. 21, 2017, 2:16 p.m.

i do not just count but i've compared the caracters between them too?

Lunazoul commented on Oct. 23, 2017, 6:03 p.m.

I dont see how i could get test case 3 wrong. Its just a simple comparison...

injust commented on Oct. 23, 2017, 7:47 p.m.

Try rereading the problem statement, especially the classification criteria.

-3

Lunazoul commented on Oct. 24, 2017, 5:57 p.m.

The problem was that i had an int scanner before a String

Frontear commented on Nov. 26, 2019, 9:07 a.m.

To be more specific, Scanner#nextInt doesn't go to the new line of the input. In order to force it onto the next line, you need to append a Scanner#nextLine to it.

I'm not sure bout why I got wrong on Test Case 1...

Read the statement again (about equal).

any suggestions?

Either use StringBuilder or process each line as you read it. Concatenating all the lines takes $O(N^2)$ ~O(N^2)~ time.
