There are five countries whose names, when spelt out in capital letters, have no enclosed spaces within the letters.
For instance, FRANCE is not acceptable because both the R and the A have enclosed areas, while LEVIK, if it was a country, has no enclosed areas and so would be acceptable.
We know that the only letters (written in capitals) which do not
possess any enclosed spaces (or areas) between them are C, E, F, G, I, J, K, L, M, N, S, T, U, V, W, X, Y, Z
By means of trial and error, we observe that the names of the
following countries can be formed by these letters.
CHILE, FIJI, YEMEN, LIECHTENSTEIN and SEYCHELLES
