shortestWordDifference.js

// Given a list of words and two words word1 and word2, return the shortest distance between these two words in the list.

// For example,
// Assume that words = ["practice", "makes", "perfect", "coding", "makes"].

// Given word1 = “coding”, word2 = “practice”, return 3.
// Given word1 = "makes", word2 = "coding", return 1.

// Note:
// You may assume that word1 does not equal to word2, and word1 and word2 are both in the list.
