Theme: Clue Symmetry and Logic (for Veep)

Author/Opus: This is the 141st puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Variation of Slitherlink rules. The loop may now intersect itself at a point (it still may not coincide anywhere). At any dot at which more than 2 segments meet, the segments must all travel straight through the dot. This example may help:

Answer String: For each marked row, enter the length in cells of each connected group inside the loop from left to right. Separate each row’s entry with a comma. Shading the loop so that each fence separates a shaded/unshaded cell can help identify what is inside. For the example, the answer would be “11,12”.
