Give me a code to minimum number of alternate subsequences required to be removed to empty a Binary String and the other steps required given the following:
Minimum number of alternate subsequences required to be removed to empty a Binary String | Function to find the minimum number of operations to empty a binary string.
Stores the resultant number of operations.
Stores the number of 0 s.
Stores the number of 1 s.
Traverse the given string.
To balance 0 with 1 if possible.
Increment the value of cn0 by 1.
To balance 1 with 0 if possible.
Increment the value of cn1.
Update the maximum number of unused 0 s and 1 s.
Print resultant count.
Driver Code"
How can the above be solved in Python?
