### 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 <string>
#include <cctype>

using namespace std;

int main() {
    int ans = 0;
    string line;
    while(cin >> line) {
        int v = 0;
        for(int i = 0; i < line.size(); ++i) {
            if(isdigit(line[i])) {
                v *= 10;
                v += line[i]-'0';
            }
            else {
                ans += v;
                v = 0;
            }
        }
        ans += v;
    }
    cout << ans << endl;
    return 0;
}
