!! This hanjie is a contactless hanjie (CLH). It is only logical with the constraint that no horizontal segment meet any vertical segment (except possibly with the corners) !!

We continue to complicate it adding some edge-logic.
Indeed, as two segments can't meet each other, we can apply edge-logic in some spots.

Examples:
- On row R6, the 2 starts at the earliest in C6, because it can't meet the 6 from C5. That allows to place part of the 6 from R6.
- (When 11 is placed) In column C14, the 5 starts at the earliest in R19, because it can neither meet the 2 from R17, nor meet the row R18.

Difficulty : *****

Tested, logical (as a CLH).
Edge-logic, smile-logic and some basics CLH-technicals can be usefull.
Good blackenage.
