You are given a string, S, and a list of words, L, that are all of the same
length. Find all starting indices of substring(s) in S that is a
concatenation of each word in L exactly once and without any intervening
characters.
For example, given:
S: "barfoothefoobarman"
L: ["foo", "bar"]
You should return the indices: [0,9].
