| ## Task | ||
|
|
||
| You'll have to translate a string to Pilot's | ||
| alphabet ([NATO phonetic alphabet](https://en.wikipedia.org/wiki/NATO_phonetic_alphabet)). | ||
|
|
||
| **Input:** | ||
|
|
||
| `If, you can read?` | ||
|
|
||
| **Output:** | ||
|
|
||
| `India Foxtrot , Yankee Oscar Uniform Charlie Alfa November Romeo Echo Alfa Delta ?` | ||
|
|
||
| **Note:** | ||
|
|
||
| - There is a preloaded dictionary that you can use, named `NATO`. It uses uppercase keys, e.g. `NATO['A']` is `"Alfa"`. | ||
| See comments in the initial code to see how to access it in your language. | ||
| - The set of used punctuation is `,.!?`. | ||
| - Punctuation should be kept in your return string, but spaces should not. | ||
| - __Xray__ should not have a dash within. | ||
| - Every word and punctuation mark should be seperated by a space ' '. | ||
| - There should be no trailing whitespace |
