1408 String Matching in an Array.js

/**
 * 
 * Example 1:

    Input: words = ["mass","as","hero","superhero"]
    Output: ["as","hero"]
    Explanation: "as" is substring of "mass" and "hero" is substring of "superhero".
    ["hero","as"] is also a valid answer.

    Example 2:

    Input: words = ["leetcode","et","code"]
    Output: ["et","code"]
    Explanation: "et", "code" are substring of "leetcode".

    Example 3:

    Input: words = ["blue","green","bu"]
    Output: []
    Explanation: No string of words is substring of another string.
