Rules
Two same-color cells are considered "connected" if they are adjacent vertically or horizontally, but not diagonally. Connected white cells form "islands", while connected black cells form the "sea". The challenge is to paint each cell black or white, subject to the following rules:
1. Each numbered cell is an island cell, the number in it is the number of cells in that island.

2.Each island must contain exactly one numbered cell.

3.There must be only one sea, which is not allowed to contain "pools", i.e. 2×2 areas of black cells.
