I just changed the behaviour of Haskell to match JS and Python. Ruby still needs to be adjusted.

Fixed.

Changed everything and then approved.

Rejected because of missing random tests.

• Only 1 fixed test.
• Missing random tests.

Rejected

• Missing random tests
• Missing fixed tests for the setter
• Missing sample tests
• extends Object is redundant

Added them, updated to JUnit 5 and approved.

Just use the function of your programming language to write something to standard out, e.g. print() in Python, console.log() in JavaScript etc.

I found some more edge cases which should be added:

test.assert_equals(has_subpattern("AA"), True)
test.assert_equals(has_subpattern("444"), True)
test.assert_equals(has_subpattern("aaabbbccccdddddddd"), False)

Done for JS, Java, Python, Haskell.

Added in remaining languages.

All languages should have such sample and fixed tests: (Seems to be already done for Haskell, Java and Python)

• test.assert_equals(has_subpattern("aaaabb"), True, 'Input: "aaaabb"')

• test.assert_equals(has_subpattern("abbb"), False, 'Input: "abbb"')

• test.assert_equals(has_subpattern("aabbbbbbaa"), True, 'Input: "aabbbbbbaa"')

• test.assert_equals(has_subpattern("bbabbaaabbaaaabb"), True, 'Input: "bbabbaaabbaaaabb"')

Fixed. Solution is now invalidated.

Added two more fixed tests and approved.

Fork that updates the random tests.

Approved it myself today after 5 years. Forgot to look for the suggestion.
