I am trying to solve
NOPAL2using the following logic,For example, if the string is
dbdccbaabaa, then sorted string will beaaaabbbccdd, so the construction will go like..a__a__a__a_ -> ab_ab_ab_ac -> abcabdabdacCan somebody point out what's wrong with my logic ? It's giving me
WAon 5/15 cases.Submission link.
I did the same thing and my solution fails on the same test cases.
Your code fails in this case
1 10 abcabcabcd.The editorialist’s solution fills in the order c3, c2 and c1 (
3k+2, 3k+1, 3k). I don't quite understand the issue but that's the only reason I thinkHere u go -> Submission link
It got accepted now. Once u form the final string, there are still some chances of getting a palindromic substring of length 3. So to handle that case, I just added a few lines of code in the end of your main logic. Happy Coding :)
Aha thanks, seems a very cool hack :)
If it would be codeforces, I guess it would still have a chance to get uphacked, or maybe there is a proof of its correctness.
I used the same logic but instead of sorting I used priority queue for tracking frequency.
