Hi guys!↵
I was trying to solve problem 327 on SGU (http://acm.sgu.ru/problem.php?problem=327) , at the moment I can't acces the link so I will describe it here : ↵
We have n (n < = 14) words with length of maximum 30 exnglish letters.↵
We have to determine the shortest string which has all of this words as subsequences and is a palindrome.↵
Example :↵
↵
4↵
abcd↵
cdef↵
efef↵
fed↵
↵
Solution : abcdefefedracba↵
↵
SPOILER ALERT : ↵
↵
It is a problem of Hamilton Cycle , but really don't know how, I think we can add some more n words, the reversed ones of the ones from input.
