### Prompt

Construct a cpp code solution to the problem outlined:

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

Output

### Response

```cpp
#include<iostream>
#include<string>
using namespace std;

int main(){
    string in;
    int sum = 0;
    while( cin >> in ){
        for( int i=0; i<in.length(); i++ ){
            if( '0' <= in[i] && in[i]<= '9' ){
                int add = 0;
                do{
                    add = add*10 + in[i]-'0';
                    i++;
                }while( i<in.length() && '0' <= in[i] && in[i] <= '9' );
                sum += add;
            }
        }
    }
    cout << sum << endl;
