Description:
The exercise contains a large list of countries from all continents around the world along with their direct neighbors (sharing a border) and their secondary neighbors (neighbors of neighbors). Flags are generated from the ISO 3166-1 alpha-2 codes, either via their Unicode symbols (especially in HTML-based output) or using the {worldflags} LaTeX package (in PDF output).
