Determine if a sentence is a pangram. A pangram (Greek: παν γράμμα, pan gramma, "every letter") is a sentence using every letter of the alphabet at least once. The best known English pangram is:
The quick brown fox jumps over the lazy dog.
The alphabet used consists of ASCII letters a to z, inclusive, and is case
insensitive. Input will not contain non-ASCII symbols.
The Scala exercises assume an SBT project scheme. The exercise solution source should be placed within the exercise directory/src/main/scala. The exercise unit tests can be found within the exercise directory/src/test/scala.
To run the tests simply run the command sbt test in the exercise directory.
For more detailed info about the Scala track see the help page.
