### Prompt

Please formulate 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 <sstream>
#include <algorithm>
using namespace std;
int main( void )
{
	int kotae = 0;
	string in;
	while ( 1 )
	{
		getline( cin, in );
		if ( cin.eof() ) break;
		for ( string::iterator it = in.begin(); it != in.end(); it++ )
			if ( !( *it >= '0' && *it <= '9' ) )
				*it = ' ';
		istringstream is( in );
		int n;
		while ( is >> n )
		{
			kotae += n;
		}
	}
	cout << kotae << endl;
	return 0;
}
