Given the input array
l with a list of strings, only keep the elements in the sequence that have a letter that's repeated at least 3 times. Like
'lessons' has 3
s letters, so it should be kept in the sequence. But,
'lesson' has only two
s letters, so it should be removed.
lwill always be a sequence, and its elements will always be strings with only alphabetical characters.
I am using the example output with Python Lists. You can use any type of sequence in your own language.
['element', 'photoshop', 'good'] -> ['element', 'photoshop'] ['happy', 'colorful', 'luggage'] -> ['luggage'] ['reference', 'tomorrow', 'today'] -> ['reference', 'tomorrow']
This is code-golf, so the shortest code in bytes wins!
