Given an array of n distinct non-empty strings, you need to generate minimal possible
abbreviations for every word following rules below.
- Begin with the first character and then the number of characters abbreviated, which
followed by the last character.
- If there are any conflict, that is more than one words share the same abbreviation, a
longer prefix is used instead of only the first character until making the map from word
to abbreviation become unique. In other words, a final abbreviation cannot map to more
than one original words.
- If the abbreviation doesn't make the word shorter, then keep it as original.
Example:
Input: ["like", "god", "internal", "me", "internet", "interval", "intension", "face", "intrusion"]
Output: ["l2e","god","internal","me","i6t","interval","inte4n","f2e","intr4n"]
Note:
- Both n and the length of each word will not exceed 400.
- The length of each word is greater than 1.
- The words consist of lowercase English letters only.
- The return answers should be in the same order as the original array.
