Can minimum number of rotations required to get the same string be greater than len/2 and less than len ever?

Revision en3, by yesnomaybe, 2020-05-02 19:27:57

Given string S, and let K be the minimum number of rotations required to get the same string.

For Example: (1) For S = "aaaa", K = 1 (2) For S = "abcabc", K = 3 (3) For S = "abcdef", K = 6

Now my question is, can there be any string for which K > len(S)/2 and K < len(S) ? If not, can someone please help me prove it?
