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.
Test cases
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.
