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.
