### Prompt

Generate 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 <bits/stdc++.h>

using namespace std;

int main()
{
    string str;
    int sum = 0, num;
    
    while (getline(cin, str)) {
        for (int i = 0; i < (int)str.size(); i++) {
            if (isdigit(str[i])) continue;
            else {
                str[i] = ' ';
            }
        }

        stringstream ss(str);
        while (ss >> num) {
            sum += num;
        }
    }
    cout << sum << endl;
    return 0;
}
