### Prompt

In CPP, your task is to solve 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 <cstdio>
#include <iostream>
using namespace std;
int main() {
    char c;
    int t = 0, ans = 0;
    while((c = getchar()) != EOF) {
        if('0' <= c && c <= '9') {
            t *= 10;
            t += c - '0';
        }
        else {
            ans += t;
            t = 0;
        }
    }
    cout << ans << endl;
}
```
