1. You are given a string and a pattern. 2. You've to check if the string is of the same structure as pattern without using any regular expressions. Note -> Check out the question video and write the recursive code as it is intended without changing signature. The judge can't force you but intends you to teach a concept.
1 <= length of str,ptr <= 20
A String str A pattern ptr
Check the sample ouput and question video.
