Example: for "France Italy" the combined length is 2078 km (between Brittany and the "heel" of the Italian "boot"). EACH COUNTRY APPEARS ONLY ONCE. Therefore "France Spain" wouldn't be a valid answer, as France was already used (and the combined length France+Spain is shorter than France+Italy). Extreme points are on the same continuous landmass (islands, exclaves and dependencies are excluded). Countries may be entered in either order.
