### Prompt

Your task is to create 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 <iostream>
#include <string>
#include <ctype.h>
using namespace std;

int main()
{
  long long int ans = 0;
  string s;
  while (cin >> s) {
    long long int tmp = 0;
    bool digit = false;
    for (unsigned int i = 0; i < s.size(); ++i) {
      if (isdigit(s[i])) {
	digit = true;
	tmp *= 10;
	tmp += (s[i] - '0');
      } else {
	if (digit) {
	  ans += tmp;
	  digit = false;
	  tmp = 0;
	}
      }
    }
    if (digit)
      ans += tmp;
  }
  cout << ans << endl;
  return 0;
}
```
