MFLAR10 - Flowers Flourish from France
Fiona has always loved poetry, and recently she discovered a fascinating poetical form. Tautograms are a special case alliteration, which is the occurrence of the same letter at the beginning of adjacent words. In particular, a sentence is a tautogram if all of its words start with the same letter.
For instance, the following sentences are tautograms:
- Flowers Flourish from France
- Sam Simmonds speaks softly
- Peter pIckEd pePPers
- truly tautograms triumph
Fiona wants to dazzle her boyfriend with a romantic letter full of this kind of sentences. Please help Fiona to check if each sentence she wrote down is a tautogram or not.
Each test case is given in a single line that contains a sentence. A sentence consists of a sequence of at most 50 words separated by single spaces. A word is a sequence of at most 20 contiguous uppercase and lowercase letters from the English alphabet. A word contains at least one letter and a sentence contains at least one word.
The last test case is followed by a line containing only a single character ‘*’ (asterisk).
For each test case output a single line containing an uppercase ‘Y’ if the sentence is a tautogram, or an uppercase ‘N’ otherwise.
Sample input: Flowers Flourish from France Sam Simmonds speaks softly Peter pIckEd pePPers truly tautograms triumph this is NOT a tautogram * Sample Output: Y Y Y Y N

Simple indeed :)
Fiona wants to write love letter to Shrek ......hahaha
can some one give special test cases..
can there be more than 1 space btw 2 words?
yes, a single word is a tautogram.
I am getting confused how to read inputs. Do i have to read it from a file or stdin?? and if it is stdin, then do I have to read all the i/p at once or reading one at a time and generating the o/p for that and then reading another i/p? please help!!
