2019-5: Doubling Up
Given a word or a list of words, return a Boolean vector where 1 indicates a word with one or more consecutive duplicated, case-sensitive, letters. Each word will have at least one letter and will consist entirely of either uppercase (A–Z) or lowercase (a–z) letters. Words consisting of a single letter can be scalars.
💡 Hint: The nest function ⊆Y could be useful.
Examples:
(your_function) 'I' 'feed' 'the' 'bookkeeper'
0 1 0 1
(your_function) 'I'
0
(your_function) 'feed'
1
(your_function) 'MY' 'LLAMAS' 'HAVE' 'BEEN' 'GOOD'
0 1 0 1 1
