Pangrams

Roy wanted to increase his typing speed for programming contests. His friend suggested that he type the sentence “The quick brown fox jumps over the lazy dog” repeatedly. This sentence is known as a pangrambecause it contains every letter of the alphabet.

After typing the sentence several times, Roy became bored with it so he started to look for other pangrams.

Given a sentence, determine whether it is a pangram.

Input Format

Input consists of a string .

Constraints
Length of  can be at most   and it may contain spaces, lower case and upper case letters. Lower-case and upper-case instances of a letter are considered the same.

Output Format

Output a line containing pangram if  is a pangram, otherwise output not pangram.

Sample Input

Input #1

We promptly judged antique ivory buckles for the next prize    

Input #2

We promptly judged antique ivory buckles for the prize    

Sample Output

Output #1

pangram

Output #2

not pangram

Explanation

In the first test case, the answer is pangram because the sentence contains all the letters of the English alphabet. The second sentence does not.

using System;
using System.Linq;

namespace Solution {
class Solution {
    static void Main(string[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT */
        string input = Console.ReadLine().Trim();
            if (input.Length >= 26)
                Console.WriteLine(PangramOrNot(input));
            else
                Console.WriteLine("not pangram");
    }
      private static string PangramOrNot(string str)
        {
            char[] alphabet = "abcdefghijklmnopqrstuvwxyz".ToCharArray();

            str = str.ToLower();

            int alphabetCount = 0;

            for (int i = 0; i < alphabet.Length; i++)
            {
                if (str.Contains(alphabet[i])) alphabetCount++;
            }

            if (alphabetCount == 26)
                return "pangram";

            return "not pangram";
        }
}
}
