# Leetcode 804 - Unique Morse Code Words

Note:

• Know how to efficently use split with map.

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.

Example:

Code:
