Write me a code to minimum substring reversals required to make given Binary String alternating and the other steps required given the following:
Minimum substring reversals required to make given Binary String alternating | Function to count the minimum number of substrings required to be reversed to make the string S alternating.
Store count of consecutive pairs.
Stores the count of 1 s and 0 s.
Traverse through the string.
Increment 1 s count.
Increment 0 s count.
Increment K if consecutive same elements are found.
Increment 1 s count.
else : Increment 0 s count.
Check if it is possible or not.
Otherwise , print the number of required operations.
Driver code.
Function Call"
How can the above be solved in Python?
