Pipe

You are working as a plumber in local company. You have been doing your job for more than twenty years, but you have never seen such a mess like this. Your customers are angry, because they do not have access to drinking water and you were called to solve this problem. When you came, you saw exactly what happened. Pipes, which are feeding water to the house, are not in right order. You must connect all pieces of a pipe together and this problem will be solved. Have fun.
