Maybe I misunderstood what you meant by "longest common prefix”. 
Presuming that A and B are arbitrary binary “strings”, then:

- by common, I presumed something that is common for both A and B
- by prefix, I presumed something that precedes something else. In this context, this would be everything that A and B have in common, from left to right, before they start to differ.

This lead me to believe that <<“Hello World”>> and <<“Hellao World”>> have only <<“Hell”>> that satisfy the above criteria.

My apologies for being presumptuous.

Kind regards
