Solution: Count Binary Substrings
Understand how to count valid binary substrings with equal numbers of consecutive zeros and ones by tracking group sizes. Learn to implement a single-pass algorithm that compares adjacent character groups to find the total count efficiently with constant space use.

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.
