### 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

### Response

```cpp
#include<iostream>
#include<string>
#include<cmath>
#include<cctype>

using namespace std;

int ExtractInt(string &s){
	int ret = 0;
	int keta = 0;
	for(int i = s.length() - 1; i >= 0; i--){
		if( isdigit(s[i]) ){
			while( isdigit(s[i]) ){
				ret += (int)pow(10, (double)keta) * (s[i] - '0');
				keta++;
				i--;
			}
			keta = 0;
		}
	}
	return ret;
}

int main(void){
	int key = 0;
	while( true ){
		string s;

		cin >> s;
		if( cin.eof() ) break;

		key += ExtractInt( s );
	}

	cout << key << endl;
	return 0;
}
