1461 - Check If a String Contains All Binary Codes of Size K\. Medium 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 indices 0, 1, 3 and 2 respectively. **Example 2:** **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 3:** **Input:** s = "0110", k = 2 **Output:** false **Explanation:** The binary code "00" is of length 2 and does not exist in the array. **Constraints:** * 1 <= s.length <= 5 * 105 * `s[i]` is either `'0'` or `'1'`. * `1 <= k <= 20`
