This is a practice problem for an upcoming contest…i cant figure out a case where my code fails to produce the correct output…can ne1 pls point out the mistake…thanks in advance…
ANAGRAM
Given an English text print out the list of words and their anagrams in their order of occurrence. Word A is an anagram of word B if it can be derived from word B by merely shuffling the letters in word B.
Important Points:
Text can contain words in upper case as well as lower case and punctuation marks
Anagrams are not to be case sensitive
The word and its anagrams are to be printed in the order of their occurrence in the text, separated by a blank.
If a word has no anagram in the text, then do not print it
If a word or its anagram occurs more than once do not print it again
Numbers are to be considered as valid words
Input:
A text containing K English words (where K <= 5000), with spaces and punctuation marks
Output:
The output should contain the word (in its order of occurrence in the text) and its set of anagrams in the text (again in their order of occurrence), separated by blanks
Each new list of words and anagrams should begin on a new line
All words in the output should be printed in lower case characters
TEST CASE:-
Parts of the world have sunlight for close to 24 hours during summer. Dan went to the north pole to lead an expedition during summer. He had a strap on his head to identify himself as the leader. Dan had to deal with the sun never going down for 42 consecutive days and his leadership strap soon became a blindfold. He wondered what kind of traps lay ahead of him.
OUTPUT:-
parts strap traps
24 42
dan and
lead deal
CODE…LINK!!!
ok yes almost there is WA did u saw that hint :: English Case:–dp,pd ap,pa dssd and after that if u get good Job do tell me if it does not has presentation error as i get presentation error with good job.

finally i alligned all
dude…in ENGLISH after every punctuation mark there is a space…as far as i know!!!
that is an ambiguity…it has not been mentioned properly in the problem statement…but i dont think we have to print any punctuations…so i have removed that too…also when i was solving the ques i saw the stats…i saw arnd 200+ ppl trying it and none had got AC!!!
maybe the test cases are faulty…not sure!!!
dude…in ENGLISH after every punc there is a space…!!!
no output…but the case does not follow english rules!!!
see this link…Spacing with Punctuation | Punctuation Rules
or maybe go to ur primary section teacher…
dude…we are speaking of ENGLISH, and in proper ENGLISH, always punctuations like “,”, “.”, “?”, “!” etc. have a space after it…and what do u mean by puncs in my program…im not writing ne english essay out there…
@kunal361 u r rude:) and eg for u : Kunal?uknal how many words here?? work on it it will give u correct answer just do it rather than telling me English lessons
sorry if i was rude…
but still im not understanding y r u telling me to try this case…also if i m unable to understand what you may want to convey…pls do explain it…
simple as that split using ? , . etc also
