### Prompt

Please create a solution in cpp 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(){

	int res=0, tmp=0;
	string str;
	
	while(cin>>str, !cin.eof()){
		
		tmp = 0;

		for(int i=0; i<str.size(); ++i){
			
			if('0'<=str[i]&&str[i]<='9'){
				tmp = tmp*10 + (int)(str[i]-'0');
			}
			else{
				res += tmp;
				tmp = 0;
			}
		}

		res += tmp;
	}
	
	cout << res << endl;
	
	return 0;
