a. (easy) What is the only U.S. state name that can be typed on a single row of keys on a standard QWERTY typewriter?

b. (harder) What are the countries,which names can be typed like in a.

c. (difficult) Same for capitals (of countries and US states).

(In reply to mostly computer solution by Charlie)

I remember La Paz(de-facto capital of Bolivia, officially it is Sucre) as the highest" capital. 

Copied and pasted:

Localiza-se no oeste do país, a 3 660 metros de altitude. Tem aproximadamente 2 087 597 habitantes. Embora Sucre continue legalmente a ser a capital do país, La Paz é a sede do governo da Bolívia desde 1898. E é ainda capital do departamento com o mesmo nome.

I liked the "approximate" number of habitants  ...
