Funny String

In this challenge, you will determine whether a string is funny or not. To determine whether a string is funny, create a copy of the string in reverse e.g. . Iterating through each string, compare the absolute difference in the ascii values of the characters at positions 0 and 1, 1 and 2 and so on to the end. If the list of absolute differences is the same for both strings, they are funny.

Determine whether a give string is funny. If it is, return Funny, otherwise return Not Funny.

For example, given the string , the ordinal values of the charcters are .  and the ordinals are . The absolute differences of the adjacent elements for both strings are , so the answer is Funny.

Solution in C# - 

class Solution 

{

    static string funnyString(string s) {

       char[] arr = s.ToCharArray();

        Array.Reverse(arr);

        string s2 = new string(arr);

        string ans = "";

        string ans2 = "";

        for(int i=0, j=0; i<s.Length-1 && j<s2.Length-1; i++,j++)

        {

            ans = ans + Math.Abs(s[i]-s[i+1]);

            ans2 = ans2 + Math.Abs(s2[j]-s2[j+1]);

        }

        if(ans.Equals(ans2))

        return "Funny";

        else

        return "Not Funny";

    }

    static void Main(string[] args) {

        TextWriter textWriter = new StreamWriter(@System.Environment.GetEnvironmentVariable("OUTPUT_PATH"), true);

        int q = Convert.ToInt32(Console.ReadLine());

        for (int qItr = 0; qItr < q; qItr++) {

            string s = Console.ReadLine();

            string result = funnyString(s);

            textWriter.WriteLine(result);

        }

        textWriter.Flush();

        textWriter.Close();

    }
