Author/Opus: This is the 170th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Variation of Battleships. Locate an unknown fleet of 1-cell wide ships into the grid. Each segment of a ship occupies a single cell, and ships do not touch each other, even diagonally. Some sea cells, without any ship segments, are given in the grid. Numbers on the right and bottom edges of the grid reveal the number of ship segments in that row or column. Numbers on the top and left of the grid indicate the number of distinct ships in that row or column.

Answer String: For each row from top to bottom, enter the number of the first column from the left where a ship segment appears (enter just the last digit for any two-digit number). If the row is empty, enter 0. Enter these numbers as a single string with no separators.

Time Standards (highlight to view): Grandmaster = 3:00, Master = 4:45, Expert = 9:30
