Hitori Rules

You will be given a grid with a symbol in each grid cell. Shade some of the grid cells, in order to fulfill the following requirements: No two shaded cells can share a side. All of the unshaded cells must form one unshaded connected component. No unshaded symbol may be in the same row and column as another of the same unshaded symbol (e.g. no two “3”s may be unshaded in the same row or column)
