Given a binary string s and an integer k.
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, 3 and 2 respectively.

Example 2:
Input: s = "00110", k = 2
Output: true

Example 3:
Input: s = "0110", k = 1
Output: true
Explanation: The binary codes of length 1 are "0" and "1", it is clear that both exist as a substring. 

Example 4:
Input: s = "0110", k = 2
Output: false
Explanation: The binary code "00" is of length 2 and doesn't exist in the array.

Example 5:
Input: s = "0000000001011100", k = 4
Output: false

 
Constraints:

1 <= s.length <= 5 * 10^5
s consists of 0's and 1's only.
1 <= k <= 20
