Objective
Your goal is to make a program that converts an input to its acronym. Your input is guaranteed to have only letters and spaces. The input will have exactly one space between words. You must output the acronym of the input.
Rules
- Your code cannot be case-sensitive(e.g.
foo
andFoo
are the same) - Your code must ignore the following words and not put them in the acronym:
and or by of
- You cannot assume that the words are all lowercase.
- The output must be entirely capitalised, with no separation between characters.
- A trailing newline is accepted but not necessary.
- If your language has an acronym function builtin, you may not use it.
