Shortest period of a string

Revision en4, by Shivram, 2017-08-15 14:15:04

Hello guys,

Is there any way to find the shortest period of a string using Z algorithm. I know of one using KMP.

EDIT:

Sorry for stating the question wrongly.

I was solving this. So the point where i got struck was: given a string, find shortest period for each prefix. Can this be solved by Z-algorithm in linear time? And also is there a way to transform Z array to LPS array and vice-versa?

Thanks in advance,

Shivram

UPDATE: SOLVED

Method

This converts Z to LPS. After that we can use the editorial method.
