This problem requires more test cases. My solution as many others would fail for a case in which the searched substring is not ordered.
Rafael, If I am not misunderstanding you, the problem asks for a continuous sub-string.
I recommend a test suite example where multiple or all of the character strings in the input are of the same length.
