Solution: Count Binary Substrings
Explore how to solve the problem of counting binary substrings that have an equal number of consecutive 0s and 1s. Understand the key insight of tracking consecutive character groups and applying the minimum group size to count valid substrings efficiently with a single pass over the string.

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.
