### 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 <sstream>
#include <string>
int main(){
	std::string s;
	std::stringstream ss;
	int a=0,i;
	while(std::cin>>s){
		for(i=0;i<(int)s.size();i++)ss<<((isdigit(s[i]))?s[i]:' ');
		while(ss>>i)a+=i;
		ss.clear();
	}
	std::cout<<a<<"\n";
}
