Title: Update README.md

```ruby
successfull_logins & failed_logins
```

That would give you logins that are both in the success and failed array.
The + operator is the one I think would fit in there.

*Here's my experiment:*

```ruby
array1 = [1, 2, 3]
array2 = [3, 4, 5, 6]

print "Intersections: \n"
print array1 & array2
print "\n"

print "Addition: \n"
print array1 + array2
print "\n"
```

*Prints:*

Intersections:
3
Addition:
1233456
