Issue types

Now that you've learned about some of the various types of message issues, your manager would like you to review some log entries and let them know what kinds of problems are being seen in the data. This information represents short sequences of either numbers or letters. Each should be in its normal order and is expected to be complete in the sequence seen. If you see a - in place of a number or letter, this means that no data was received at that time (but might be seen later).
