### 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>
using namespace std;

int main()
{
	int sum = 0;

	while(true){
		char c;
		cin.get(c);
		if(cin.eof())
			break;

		if(c>='0'&&c<='9'){
			int num = c-'0';
			while(true){
				cin.get(c);
				if(!(c>='0'&&c<='9'))
					break;
				num = num*10+(c-'0');
			}
			sum += num;
		}
	}

	cout << sum << endl;

	return 0;
}
