### Prompt

Please formulate a cpp solution to the following problem:

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

### Response

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

int main(){
    string ss;
    int sum = 0;
    while( cin >> ss ){
        for( string::iterator it = ss.begin(); it != ss.end(); it++){
            if( isdigit(*it) ){
                int a = *it - '0';
                while( ++it != ss.end() && isdigit(*it) ){
                    a *= 10;
                    a += *it - '0';
                }
                if( it == ss.end() ) it--;
                sum += a;
            }
        }
    }
    cout << sum << endl;
    return 0;
