Need some help to solve Minimum Rotations(string) problem.

Revision en2, by Newaj_69, 2017-10-22 19:10:59

I was trying to solve the problem http://www.spoj.com/problems/MINMOVE/ but unfortunately couldn't. My solution idea is:

1.First of all I checked whether all the character is same or not. If it is same then the answer is O. Example: aaa answer should be O.

2.Otherwise, I have concatenate the string at the back of the string and then added a "$" at last.

3.Then I build the suffix array (O*Log(N)).

4.At last I traverse the suffix array whenever I got a value in the suffix array less then the string.size() I have printed the value.

Now, I have no idea what to do.Any help or suggestions would be appreciated.
