+# Pangram
+
+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.
