cannot pass the final validators7: the incremental options, I try to pass all the other testcases, I cannot pass the 7th validators may be the reson I still cannot figure out this case:
verbose
verb
verbose
verb
verbose
why it outputs
verbo
verb
verbo
verb
verbo
in my thought it should not be accepted because they existed the same words, and how can I tell if the testcases have the same words? I think it’s the reason I cannot pass it.
any suggestion for me?
Because “verbo” is enough to match “verbose”.

I’m stuck at the same place as you. How did you solve it?
Found the issue - I wasn’t handling duplicates very well.

this case my algo do well, as other in task, but submission fails 2,4,5 validators. any idea ?
You may send your code (with its language) in private, I might send back what’s wrong.
Found:
LIONEL
Expected:
LIO
I understand, there’re duplicates, but in this case the prefix is the whole word, no ? How come it’s LIO 
I don’t know what you mean by duplicates, but the answer is LIO because there’s LINDSAY in the list (assuming you’re talking about Test 6 “Pierre, Paul, Jacques & co.”).
