I was trying to solve the problem but unfortunately couldn't. My solution idea was:

1.First of all I checked whether all the character is same or not. If it is same then the answer is 0. Example: aaa answer should be 0.

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 (n*log(n)).

4.At last I traversed the suffix array whenever I got a value in the suffix array less then the string.size()/2 then I printed the value.

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