# Pangram Welcome to Pangram on Exercism's Bash Track. If you need help running the tests or submitting your code, check out `HELP.md`. ## Introduction You work for a company that sells fonts through their website. They'd like to show a different sentence each time someone views a font on their website. To give a comprehensive sense of the font, the random sentences should use **all** the letters in the English alphabet. They're running a competition to get suggestions for sentences that they can use. You're in charge of checking the submissions to see if they are valid. ~~~~exercism/note Pangram comes from Greek, παν γράμμα, pan gramma, which means "every letter". The best known English pangram is: > The quick brown fox jumps over the lazy dog. ~~~~ ## Instructions Your task is to figure out if a sentence is a pangram. A pangram is a sentence using every letter of the alphabet at least once. It is case insensitive, so it doesn't matter if a letter is lower-case (e.g. `k`) or upper-case (e.g. `K`). For this exercise we only use the basic letters used in the English alphabet: `a` to `z`. ## Source ### Created by - @jaggededgedjustice ### Contributed to by - @bkhl - @budmc29 - @glennj - @guygastineau - @IsaacG - @kotp - @sjwarner-bp - @Smarticles101 - @ZapAnton ### Based on Wikipedia - https://en.wikipedia.org/wiki/Pangram
