In this problem, a valid human name is defined to contain the string of the first name, followed by a space, and then by the string of the last name. The string of first/last name must start with a capital letter and consist only of characters that are letters (i.e. no numbers, symbols, etc). For instance, "John Doe" is valid but "John doe". "John Doe-II" and "John Doe I" are invalid.
