696 - Count Binary Substrings\. Easy Give a binary string `s`, return the number of non-empty substrings that have the same number of `0`'s and `1`'s, and all the `0`'s and all the `1`'s in these substrings are grouped consecutively. Substrings that occur multiple times are counted the number of times they occur. **Example 1:** **Input:** s = "00110011" **Output:** 6 **Explanation:** There are 6 substrings that have equal number of consecutive 1's and 0's: "0011", "01", "1100", "10", "0011", and "01". Notice that some of these substrings repeat and are counted the number of times they occur. Also, "00110011" is not a valid substring because all the 0's (and 1's) are not grouped together. **Example 2:** **Input:** s = "10101" **Output:** 4 **Explanation:** There are 4 substrings: "10", "01", "10", "01" that have equal number of consecutive 1's and 0's. **Constraints:** * 1 <= s.length <= 105 * `s[i]` is either `'0'` or `'1'`.
