ONLY if their group size (or array length) is equal to the number of shared letters in each beginning

• solutions, some -> beginning = so (2 letters, 2 words) OK
• only -> beginning = o (1 letter, 1 word) OK
• are -> beginning = ar (2 letters, 1 word) not OK
• answers -> beginning = an (2 letters, 1 word) not OK

only -> beginning = o (1 letter, 1 word) OK \\\ Why 'o'? Its only one word here wtf??

are -> beginning = ar (2 letters, 1 word) not OK \\\ Why 'ar'? Its only one word here wtf??

answers -> beginning = an (2 letters, 1 word) not OK \\\ Why 'an'? Its only one word here wtf??

Whats the logic here? Why dont author explain this in the description..

• There is 1 word that starts with o -> {"o": ["only"]} -> 1 letter prefix, 1 word -> 1 = 1 -> OK
• There are 2 words that start with a -> {"a": ["are","answers]} -> 1 letter prefix, 2 words -> 1 < 2 -> we will add more letters to make subdivisions
• There is 1 word that starts with ar -> {"ar": ["are"]} -> 2 letters prefix, 1 word -> 2 > 1 -> Not OK
• There is 1 word that starts with an -> {"an": ["answers"]} -> 2 letters prefix, 1 word -> 2 > 1 -> Not OK
• There are 2 words that start with s -> {"s": ["some","solutions]} -> 1 letter prefix, 2 words -> 1 < 2 -> we will add more letters to make subdivisions
• There are 2 words that start with so -> {"so": ["some","solutions]} -> 2 letter prefix, 2 words -> 2 = 2 -> OK
• we take all the OK's in one final sorted array -> ["only", "solutions", "some"]
• Mic drop!

Endeed is added on the test cases an not specify on the description. I added a note in the description, if it helps.

I was wondering if I don't return anything in that case or what to do from reading the description
