### Prompt

Develop a solution in CPP 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 str;

    int sum = 0;
    while( cin >> str )
    {
        int digit = 1;
        for( int i = str.size() - 1; i >= 0; i-- )
        {
            if( '0' <= str[i] && str[i] <= '9' )
            {
                sum += ( str[i] - '0' ) * digit;
                digit *= 10;                        
            }
            else
                digit = 1;
        }
    }

    cout << sum << endl;

    return 0;
}
