### Prompt

Develop a solution in CPP 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 <bits/stdc++.h>
using namespace std;


int main() {
    string s;
    int ans = 0;
    while(cin >> s) {
        int pre_digit = 1;
        int n = s.size();
        for(int i = n-1; i>=0; i--) {
            if(isdigit(s[i])) {
                ans += (s[i] - '0') * pre_digit;
                pre_digit *= 10;
                continue;
            }
            pre_digit = 1;
        }
    }

    cout << ans << endl;

    return 0;
}
