Question

This is the code I get from the internet about how to make a jumbled string. Some of them are confused. Can I get pseudocode for that? (C++ please)

string Jumblestring(string input)
{
   int count = input.length();
   int i, j, mid;
   string temp = "";
   for (i = 0; i < count; i++)
       temp.append(" ");
   if (count % 2 == 1)
       mid = count / 2;
   else
       mid = count / 2 - 1;
   for (i = 0; i <= mid; i++)
       temp[i] = input.at(mid - i);
   for (i = 2, j = 0; i < count; i++, j++)
       temp[i] = input.at(count - 1 - j);
   return temp;
}

Answer 1

declare function jumbleString with parameter input string

set count to store the length of input string

declare i, j, mid

set temp string to ""(empty)

for i in range 0 to count

append " "(space) in the temp

end for

if count is odd

mid = count/2

else

mid = count/2-1

for i in range 0 to mid

set temp[i] to input[mid-i]

end for

for i in range 2 to count and j in range 0 to count

set temp[i] to input[count-1-j]

end for

return temp string

end jumbleString function
