Give me a code to length of the longest substring with equal 1 s and 0 s and the other steps required given the following:
Length of the longest substring with equal 1 s and 0 s | Function to check if a contains equal number of one and zeros or not.
Function to find the length of the longest balanced substring.
Driver code.
Function call"
How can the above be solved in Python?
