Question

Design a program in pseudocode that asks the user to enter a string containing a series of ten single-digit numbers with nothing separating them. The program should display the sum of all the single digit numbers in the string except for the highest value digit. You may only use one main module and one sorting function; otherwise, do not modularize your program.

For example, if the user enters 5612286470, the sum would be 33. (0+1+2+2+4+5+6+6+7)

If there are multiple highest value digits then just leave out one of them... 0000000999 sum would be 9.

Answer 1

Please find below code containing 2 modules one for bubble sort and the other to compute total as per requirement, Sorting helps to eliminate last largest number and in main module we compare and exclude the repetition and consider only once for totaling. Please comment if more information required:

function sort(array ar)
{
   for i=0 to N-2
       for j=0 to N-2
           if(a(j)>a(j+1);
           temp=a(j);
           a(j)=a(j+1);
           a(j+1)=temp;
           end if
       end for
   end for
   return ar;
}

function main
{

   input string abc;
   abc = sort(abc);
   int total = 0;

   for (h=0;h<abc.count-2;h++)
   {
       if(string(h) is not equal to string(h+1) and string(h) is not equal to abc.count-2
       {
           total=total + convert.toinet32(abc(h));
       }
   }

   print total;
}
