### Prompt

Please provide a CPP coded solution to the problem described below:

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>
using namespace std;

int main(){
	string hyu, num = "";
	int len, ans=0, z;
	while(getline(cin,hyu)){
		len = hyu.size();
		for(int i=0;i<len;i++){
			z = hyu[i];
			if(z>=48&&z<=57){
				num += hyu[i];
			}
			else {
				try
				{
					ans += stoi(num);
				}
				catch (const std::exception&)
				{}
				num = "";
			}
		}
	}
	cout << ans << endl;
	return 0;
}
