### 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 <iostream>
#include <cstdio>
#include <cmath>
using namespace std;

bool isNumber(char a) {
    return(a >= '0' && a <= '9');
}

int calc(string a) {
    int sum = 0;
    int keta = 0;
    for(int r = (int)a.size() - 1; r >= 0; r--) {
        if(isNumber(a[r])) {
            sum += (a[r] - '0') * pow(10, keta);
            keta++;
        } else keta = 0;
    }
    return(sum);
}

int main(void) {
    string input;
    int sum = 0;
    while(cin >> input) {
        sum += calc(input);
    }
