### Prompt

Create a solution in cpp for 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 <string>

using namespace std;

int main() {
    int ans = 0, num;
    string s;
    while (cin >> s) {
        num = 0;
        for (int i = 0; i < s.size(); i++) {
            if ('0' <= s[i] && s[i] <= '9') {
                num = num * 10 + (s[i] - '0');
            }
            else {
                ans += num;
                num = 0;
            }
        }
        ans += num;
    }
    cout << ans << endl;

    return 0;
}
