Given a list of words and two words word1 and word2, return the shortest distance between these two words in the list.
Example:
Assume that words = ["practice", "makes", "perfect", "coding", "makes"].
Input: word1 =“coding”, word2 =“practice”Output: 3
Input: word1 ="makes", word2 ="coding"Output: 1
Note:
You may assume that word1 does not equal to word2, and word1 and word2 are both in the list.
