Solution: Count Binary Substrings
Explore how to count non-empty binary substrings containing equal numbers of 0s and 1s grouped consecutively by tracking consecutive character groups. Understand the linear time approach that calculates valid substrings at group boundaries using minimal space and step-by-step logic.

Statement
Given a binary string s, return the count of non-empty substrings that satisfy both of the following conditions:
The substring contains an equal number of
'0's and'1's.All
'0's and all'1's within the substring are grouped consecutively (i.e., no interleaving of the two characters).
Substrings that appear multiple times are counted once for each occurrence.
