# Phone Number
|
|
|
|
Write a program that cleans up user-entered phone numbers so that they can be sent SMS messages.
|
|
|
|
The rules are as follows:
|
|
|
|
- If the phone number is less than 10 digits assume that it is bad
|
|
number
|
|
- If the phone number is 10 digits assume that it is good
|
|
- If the phone number is 11 digits and the first number is 1, trim the 1
|
|
and use the last 10 digits
|
|
- If the phone number is 11 digits and the first number is not 1, then
|
|
it is a bad number
|
|
- If the phone number is more than 11 digits assume that it is a bad
|
|
number
|
|
|
|
We've provided tests, now make them pass.
|
|
|
|
Hint: Only make one test pass at a time. Disable the others, then flip
|
|
each on in turn after you get the current failing one to pass.
|
|
|
|
To run the tests simply run the command `go test` in the exercise directory.
|
|
|
|
If the test suite contains benchmarks, you can run these with the `-bench`
|
|
flag:
|
|
|
|
go test -bench .
|
|
|
|
