ICPC North America Qualifier 2015, Problem F
A pangram is a phrase that includes at least one occurrence of each of the ~26~ letters, ~a \dots z~. You're probably familiar with this one:
The quick brown fox jumps over the lazy dog.
Your job is to recognize pangrams. For phrases that don't contain every letter, report what letters are missing. We'll say that a particular letter occurs in the phrase if it occurs as either uppercase or lowercase.
Input starts with a line containing an integer ~1 \le N \le 50~. The next ~N~ lines are each a single phrase, possibly containing uppercase and lowercase letters, spaces, decimal digits and punctuation characters
". Each phrase contains at least one and no more than ~100~ characters.
For each input phrase, output
pangram if it qualifies as a pangram. Otherwise, output the word
missing followed by a space and then the list of letters that didn't occur in the phrase. The list of missing letters should be reported in lowercase and should be sorted alphabetically.
