In English, there is the
fun and simple difference between
a: you use
an when preceding a word starting with a vowel sound, and
a when the word starts with a consonant sound.
For the sake of simplicity in this challenge,
an precedes a word that starts with a vowel (
a precedes a word that starts with a consonant.
A string comprising only printable ASCII characters, with
[?] appearing in places where you must choose to insert
[?] will always appear before a word. You can assume that the sentence will be grammatically correct and formatted like normal.
The input string with
[?] replaced with the appropriate word (
a). You do have to worry about capitalization!
When to Capitalize
Capitalize a word if it is preceded by no characters (is the first one in the input) or if it is preceded by one of
.?! followed by a space.
Input: Hello, this is [?] world! Output: Hello, this is a world! Input: How about we build [?] big building. It will have [?] orange banana hanging out of [?] window. Output: How about we build a big building. It will have an orange banana hanging out of a window. Input: [?] giant en le sky. Output: A giant en le sky. Input: [?] yarn ball? [?] big one! Output: A yarn ball? A big one! Input: [?] hour ago I met [?] European. Output: A hour ago I met an European. Input: Hey sir [Richard], how 'bout [?] cat? Output: Hey sir [Richard], how 'bout a cat?
This is code-golf, so shortest code in bytes wins!
