String subpattern recognition I
In this kata you need to build a function to return either true/True
or false/False if a string can be seen as the repetition of a
simpler/shorter subpattern or not.
For example
has_subpattern(“a”) == False #no repeated pattern
has_subpattern(“aaaa”) == True #created repeating “a”
has_subpattern(“abcd”) == False #no repeated pattern
has_subpattern(“abababab”) == True #created repeating “ab”
has_subpattern(“ababababa”) == False #cannot be entirely reproduced repeating a pattern
Strings will never be empty and can be composed of any character (just consider upper- and lowercase letters as different entities) and can be pretty long (keep an eye on performances!).
