Cooking Connect

The chef decided to clean up his kitchen and asks you to help him in the game Cooking Connect. Recently, he began to notice that some kitchen utensils and household appliances exist in two copies. This is not necessary, you need to select pairs of the same and then decide what to do with it. Each time, a set of tiles will appear in front of you with pots, pans, toasters, food processor elements, blenders and other devices located on them, which greatly facilitate the work in the kitchen. Your task is to look for identical pairs and connect them with lines at right angles. If other elements located on the field in Cooking Connect allow it.
