### Prompt

In Cpp, your task is to solve 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<math.h>

using namespace std;

int main(void)
{
	int ans=0;
	while(1)
	{
		string s;
		cin>>s;
		if(cin.eof())break;
		int k=0;
		for(int i=s.length()-1;i>=0;i--)
		{
			if('0'<=s[i]&&s[i]<='9')
			{
				ans+=pow(10.0,k)*(s[i]-'0');
				k++;
			}
			else k=0;
		}
	}
	cout<<ans<<endl;
}
