Creating, iterating and comparing an array with a database?

Question

Arrays

The point is, there is a list of emails, they need to be sorted through the database and these emails can be found, but only those that have a password field. You need to somehow make an array from the list of emails, and then brute force compare them with the database and find only those who have emails.
Db.getCollection("users").find(
{
"email" : "here you need to sort through
the list of emails",
"password" : {
"$exists" : true
}
}
);
