Pangram Patrol

A pangram is a sentence using every letter a–z at least once — like the famous quick brown fox one. 🦊

You get a lowercase sentence (letters and spaces). Print pangram if all 26 letters appear, or missing letters.

Example:

Input: sentence = "the quick brown fox jumps over the lazy dog" Output: pangram

Collecting the letters into a set covers all 26 different letters of the alphabet.
