Consider the following string: EFEIEDKKTIGTELIYLIKKNG. I have written a regular expression to match the portion between Ks (KKTIGTELIYLIKK) and assign it to different capture groups. My regex is (?=(K+[^K]+K+)) and yields two substrings, KTIGTELIYLIKK and KKTIGTELIYLIKK.
Now, how can I improve it to detect multiple Ks at the end as well? What I would like to detect is KTIGTELIYLIKK, KTIGTELIYLIK, KKTIGTELIYLIK and KKTIGTELIYLIKK. Is it even possible?
