804. Unique Morse Code Words
Question
International Morse Code defines a standard encoding where each letter is mapped to a series of dots and dashes, as follows:
'a'
maps to".-"
,'b'
maps to"-..."
,'c'
maps to"-.-."
, and so on.
For convenience, the full table for the
26
letters of the English alphabet is given below:
[".-","-...","-.-.","-..",".","..-.","--.","....","..",".---","-.-",".-..","--","-.","---",".--.","--.-",".-.","...","-","..-","...-",".--","-..-","-.--","--.."]
Given an array of strings
words
where each word can be written as a concatenation of the Morse code of each letter.
- For example,
"cab"
can be written as"-.-..--..."
, which is the concatenation of"-.-."
,".-"
, and"-..."
. We will call such a concatenation the transformation of a word.
Return the number of different transformations among all words we have.
