* On every loop of `while(true)` we check:
* 1. If all elements in group have same head -> extract it to common head,
* 2. If all elements in group have same tail -> extract it to common tail,
* 3. If some elements have common head -> create sub group of this elements, and put there head as common head of group,
* 4. Same for tails.
* If none of previous happen - we stop loop.
* Then check if current group has empty entry and convert it to optional (like `(a|b|) -> (a|b)?`).
* Then for every child group of current group we run same loops.
