The Prussian city of Königsberg (now the Russian City of Kaliningrad) was located on the Pregel river. The river divided the city into four separate landmasses (marked as A,B,C,D in the figure). These landmasses were linked by seven bridges (marked 1 to 7 in the figure below). Starting at one land area (A or B or C or D), the townspeople wondered if it was possible to plan a walk so that you cross each bridge exactly once. What do you think?
