### Prompt

Develop a solution in cpp to the problem described below:

The new PIN is hard to remember. I was told that I shouldn't take notes, but I don't think I can remember them. Therefore, I decided to embed a numerical value in the text and make a note of the PIN. Here, the sum of all the numbers is the PIN.

Create a program that reads the memorandum and outputs the PIN code.



Input

Sentences with embedded positive integers are given over multiple lines. Each line is a character string containing single-byte alphanumeric characters, symbols, and spaces, or a blank line. However, you are guaranteed to enter no more than 80 characters per line and a PIN of 10,000 or less.

Output

The PIN (the sum of positive integers in the text) is output on one line.

Example

Input

Thereare100yenonthetable.Iam17yearsold.
Ishouldgohomeat6pm.


Output

123

      while((i<s.size())&&(s[i]<'0'||'9'<s[i]))i++;
      if(!(i<s.size()))continue;
      while((i<s.size())&&(!(s[i]<'0'||'9'<s[i]))){
        tmp=tmp*10;
        tmp=tmp+int(s[i]-'0');
        i++;
      }
      ans=ans+tmp;
