[cs615asa] Part 3 Wrong Answer for Test 2

[Andrew Neurohr]

For the second test (your-tool -b -d zh 3.gz), I get 12264642375 as
the output using the pattern ^zh[\. ], but the expected output is:
12388808716. I was able to get this answer by using the pattern ^zh
instead, but this could match non-zh domains as well, so it is not
correct. Was anyone able to get the expected output while only
matching zh domains?
