Given a string and a list of words, find all the starting indices of substrings in the given string that are a concatenation of all the given words exactly once without any overlapping of words. It is given that all words are of the same length.
Example 1:
Input: String="catfoxcat", Words=["cat", "fox"]
Output: [0, 3]
Explanation: The two substring containing both the words are "catfox" & "foxcat".
Example 2:
