### Prompt

Create a solution in CPP for 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>

using namespace std;

int main(){
        string s;
        int sum = 0;
        while(cin >> s){
                int n = 0;
                int idx = 0;
                for(int i = 0; i < s.size(); i++){
                        if('0' <= s[i] && s[i] <= '9') n = n*10+s[i]-'0';
                        else if(n){
                                sum += n;
                                n = 0;
                        }
                }
                sum += n;
        }
        cout << sum << endl;
}
