### 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<iostream>
#include<string>
using namespace std;

int main() {
	string s;
	int sum = 0;
	while (getline(cin, s)) {
		string sa;
		for (int i = 0;i < s.size();i++) {
			if (s[i] >= '0'&&s[i] <= '9') {
				sa.push_back(s[i]);
			}
			else {
				if (i != 0 && s[i - 1] >= '0'&&s[i - 1] <= '9') {
					int a = stoi(sa);
					sum += a;
					sa.clear();
				}
			}
		}
		if (!sa.empty() && sa[sa.size() - 1] >= '0'&&sa[sa.size() - 1] <= '9') {
			int a = stoi(sa);
			sum += a;
			sa.clear();
		}
	}
	cout << sum << endl;
	return 0;
}
