Give me a code to lexicographically smallest permutation of [ 1 , N ] based on given Binary string and the other steps required given the following:
Lexicographically smallest permutation of [ 1 , N ] based on given Binary string | Function to generate the lexicographically smallest permutation according to the given criteria.
Stores the resultant permutation.
Initialize the first elements to 1.
Traverse the given string S.
Number greater than last number.
Number equal to the last number.
Correct all numbers to the left of the current index.
Printing the permutation.
Driver Code"
How can the above be solved in Python?
