algorithm - How to detect palindrome cycle length in a string? -

-

suppose string "abaabaabaabaaba", palindrome cycle here 3, because can find string aba @ every 3rd position , can augment palindrome concatenating number of "aba"s string.

i think it's possible detect efficiently using manacher's algorithm how?

you can find searching string s in s+s. first index find cycle number want (may entire string). in python like:

in [1]: s = "abaabaabaabaaba"  in [2]: print (s+s).index(s, 1) 3

the 1 there ignore index 0, trivial match.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
