Problem -> Problem

I am trying something similar to digit dp where we need to find the number of numbers in the range a to b satisfying some property, just in this case we have strings.

My helper function is actually calculating the number of good strings which are lexicographically less than or equal s and do not contain the substring evil.

Then I simply subtract the answer for two cases.

Can someone please help me in this problem.

Spoiler

This solution only passes 15 test cases. Help me please.
