AssertionError: Items in the first set but not the second:

Question

I only get this error in the new tests. I cannot find what might be the reason causing the error. Any help is appreciated.

Answer 1

They only added 1 new test for checking the cache. So I assume there's something wrong with the logic of your code. Please provide the log of errors.

Answer 2

The new tests added a check on the keys. In fact in these tests the keys can contain identical characters inside such as "aca". Check that your algorithm does not mistakenly recognize anagrams when you are in this case, for example "cca" is not an anagram of "aca".

Answer 3

In the first tests the letters that had to be searched where all different making the process significantly easier, new tests added more complex cases the require improvements from your original algorithm, it's normal that you pass the first set and not the second.

Here is an example of a new test and the rules applied to solve it https://q2a.di.uniroma1.it/assets/fondamenti-23-24/multichar.log?v=0
