### 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 <sstream>
using namespace std;

int main(){
	string s, is;
	int n, sum = 0;

	while ( cin >> s ){
		int index = 0;
		while ( !( index == s.size() ) ){
			if ( s[ index ] >= '0' && s[ index ] <= '9' ){
				int len = 1;
				while (  s[ index + len ] >= '0' && s[ index + len ] <= '9' ){
					++len;
				}
				string is( s, index, len );
				istringstream iss( is );
				iss >> n;
				sum += n;
				index += len;
			}else{
				++index;
			}
		}
	}

	cout << sum << endl;

	return 0;
}
```
