### 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>
using namespace std;

int addCharNum(string s, int *i){
  int n = 0;
  int j;
  for (j = *i; '0' <= s[j] && s[j] <= '9' && j < s.size(); j++){
    n *= 10;
    n += s[j] - '0';
  }
  *i = j;
  return n;
}

int main() {
  int sum = 0;
  int i;
  string s;
  while(cin>>s) {
    for(i=0;i<s.size();i++) {
      if('0' <= s[i] && s[i] <= '9') {
        sum += addCharNum(s, &i);
      }
    }
  }
  cout << sum << endl;
}
```
