### Prompt

Your task is to create a Cpp solution 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 argc, char** argv) {
    int secretNum = 0;
    string str;
    while(getline(cin, str)) {
        for(unsigned int i=0; i<str.size(); ++i) {
            if(str[i] < '0' || '9' < str[i]) {
                str[i] = ' ';
            }
        }
        stringstream ss(str);
        int j;
        while(ss >> j) {
            secretNum += j;
        }
    }
    cout << secretNum << endl;
    return 0;
