Programming Interview Question

Program to print sum of given string where

a=0, b=1, c= a+b, d= b+c, e= c+d ….  z= x+y

Example:

Input:     a=0 b=1

               String “Question”

Output:  Sum of Given string : 15151

      int a, b;

            string strString = "abcdefghijklmnopqrstuvwxyz";

            int sum = 0;

            int indx;

            string strEntered;

            a = int.Parse(Console.ReadLine());

            b = int.Parse(Console.ReadLine());

            strEntered = Console.ReadLine().ToLower();

            int[] arr = new int[26];

            arr[0] = a;

            arr[1] = b;

            for (int i = 2; i < arr.Length; i++)

            {

                arr[i] = arr[i - 2] + arr[i - 1];

            }

            for (int i = 0; i < strEntered.Length; i++)

            {

                indx = strString.IndexOf(strEntered.Substring(i, 1), 0);

                sum += arr[indx];

            }

            Console.WriteLine("Sum of " + strEntered + " is :" +                        sum.ToString());

            Console.ReadLine();
