What is a code to maximum length of balanced string after swapping and removal of characters and the other steps required given the following:
Maximum length of balanced string after swapping and removal of characters | Function to return the length of the longest balanced sub - string.
To store the count of parentheses.
Traversing the string.
Check type of parentheses and incrementing count for it.
Sum all pair of balanced parentheses.
Driven code"
How can the above be solved in Python?
