Hello everyone,

The problem description says that first you enter the phone number, then the number of words in the dictionary, then the dictionary itself, then -1.

However, in the input example the first test looks like this:

7325189087
5
it
your
reality
real
our

And then the second input begins.

My question: why is there no -1 in the first example?

-1 ends the whole input, ie. there will be no more phone numbers after -1.
