### 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

123

### Response

```cpp
#include <bits/stdc++.h>
using namespace std;

using db = double;
using ll = long long;
using vi = vector <int>;
#define op operator
#define pb push_back

int main() {
	cout << fixed << setprecision(9);
	ios :: sync_with_stdio(0);

	int ans = 0;
	for(string s; getline(cin, s); ) {
		s += ' '; string t = "";
		for(char c : s)
			if(isdigit(c))
				t += c;
			else if(t.size()) {
				ans += stoi(t);
				t = "";
			}
	}
	cout << ans << '\n';

	return 0;
}
```
