### Prompt

Your challenge is to write 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

Output

### Response

```cpp
#include <iostream>
#include <sstream>
using namespace std;
#define rep(i, n) for (int i = 0; i < (int)(n); i++)
typedef long long Int;

int main() {
    Int ans = 0;
    string s;
    while (getline(cin, s)) {
        rep (i, s.size()) if (!isdigit(s[i])) s[i] = ' ';
        istringstream sin(s);
        Int a;
        while (sin >> a) ans += a;
    }
    cout << ans << endl;
    return 0;
}
```
