Write a function or program that takes as its input a string and prints a truthy value if the string is a pangram (a sequence of letters containing at least one of each letter in the English alphabet) and a falsey value otherwise.
Case of letters should be ignored; If the string is
abcdefghijklmnopqrstuvwXYZ, then the function should still return a truthy value. Note that the string can contain any other characters in it, so
123abcdefghijklm NOPQRSTUVWXYZ321 would return a truthy value. An empty input should return a falsey value.
AbCdEfGhIjKlMnOpQrStUvWxYz ==> True ACEGIKMOQSUWY BDFHJLNPRTVXZ ==> True public static void main(String args) ==> False The quick brown fox jumped over the lazy dogs. BOING BOING BOING ==> True
This is code golf. Standard rules apply. Shortest code in bytes wins.
