using python feels like cheating :)

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");

One liner in javascript

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

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

My solution in c:

include

include

include

include

int main() { int a[26]={0}; int i,n,c=0; char *s=(char *)malloc(10240*sizeof(char)); scanf("%[^\n]s",s); for(i=0;s[i]!='\0';i++) { int k=s[i]; if(k>=97 && k<=122) { n=k-97; a[n]++; } else if(k>=65&&k<=91) { n=k-65; a[n]++;

    }


}
for(i=0;i<=25;i++)
    {
    if(a[i]!=0)
        c++;
}
if(c==26)
    {
    printf("pangram");

}
else
    printf("not pangram");

return 0;

}
