### Prompt

Construct a cpp code solution to the problem outlined:

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.

Output

123

### Response

```cpp
#include <iostream>
using namespace std;

string s;
int i;

int char2num(){
    int n = 0;
    for (; '0' <= s[i] && s[i] <= '9' && i < s.size(); i++){
	n *= 10;
	n += s[i] - '0';
    }
    return n;
}

int main(){

    int n = 0;
    while (cin >> s){
	for (i = 0; i < s.size(); i++)
	    if ('0' <= s[i] && s[i] <= '9') n += char2num();
    }
    cout << n << endl;
}
