### 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>
#include <cstdlib>

using namespace std;

int main()
{
    size_t sum = 0;
    string s;
    while( cin >> s ) {
        for( auto it=s.cbegin(); it<s.cend(); ++it )
        {
            if ( *it >= '0' && *it <= '9' ) {
                string t;
                t += *it;
                for( it=it+1; it < s.cend() && *it >= '0' && *it <= '9'; ++it )
                    t += *(it);

                sum += atoi( t.c_str() );
            }
        }
