### 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 <sstream>
#include <string>
using namespace std;

int main() {
    long long sum = 0;
    string line;
    while (getline(cin, line)) {
        line.erase(0, line.find_first_of("0123456789"));
        while (line.empty() == false) {
            istringstream ss(line);
            int i;
            ss >> i;
            sum += i;
            line.erase(0, line.find_first_not_of("0123456789"));
            line.erase(0, line.find_first_of("0123456789"));
        }
    }
