Return True if every binary code of length k is a substring of s. Otherwise, return False. Example 1: Input: s = "00110110", k = 2 Output: true Explanation: The binary codes of length 2 are "00", "01", "10" and "11". They can be all found as substrings at indicies 0, 1...

then return its index, otherwise return-1. However, the array size is unknown to you. You may only access the array using anArrayReaderinterface, whereArrayReader.get(k)returns the element of the array at indexk(0-indexed).
