How it is calculated
The match is case-sensitive, and spaces at the ends of a line are trimmed. “Pear” and “pear” are different lines.
Shared = lines that are in both lists
Where the numbers come from
- First list
- Second list
Example
If the left side is apple and pear, and the right is pear and plum, the shared item is pear.
