using python feels like cheating :)

One liner in javascript

javascript
function pangrams(s) {
    return new Set(s.toLowerCase()).size > 26 ? "pangram":"not pangram";
}

Java simple code..

     Scanner sc = new Scanner(System.in);
    String s= sc.nextLine();
    s = s.toLowerCase();
   HashSet<Integer> h = new HashSet<Integer>();
    for (int i = 0; i < s.length(); i++) {
        if(s.charAt(i)!=' '){
            int put = (int)s.charAt(i);
            h.add(put);
        }
    }
    if(h.size()==26)
        System.out.println("pangram");
    else
        System.out.println("not pangram");

import string 
print ["not pangram", "pangram"][set(string.ascii_lowercase).issubset(set(raw_input().lower()))]

This is way too easy in Ruby...the editorial solution is overly complex...
