SOLVED! But anyway, I want to know on which part you'd possibly make optimizations.. In case your method differs with mine it might be a pretty useful insight to know ^_^
String concatenation may take a lot of time, as it copies the whole string
a
, add a char, then write the resulting string toa
(This actually depends on some factor, such as the language, compiler, etc, I dont really understand about that too). Instead of building the stringans
, you can decide whether an answer exist (thed
value in your code) and if it does, print the output as you go through the arraycnt[]
twice, one for the first half of the answer, and the other for the second half.Relevant blog : https://mirror.codeforces.com/blog/entry/94701
