### 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 <bits/stdc++.h>

using namespace std;

int main() {
    int ans = 0;
    string s;
    while (getline(cin, s)) {
        int sz = s.size(), l, r;
        for (int i = 0; i < sz; i++) {
            if (!isdigit(s[i])) continue;
            l = i;
            while (isdigit(s[++i]));
            r = i;
            ans += atoi(s.substr(l, r - l).c_str());
        }
    }

    cout << ans << endl;

    return 0;
}
