### Prompt

Your task is to create 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>
using namespace std;

int getInt( string str ){
    int p = 1;
    int sum = 0;
    for ( int i = str.size()-1; i >= 0; i-- ){
	sum += (str[i]-'0')*p;
	p *=10;
    }
    return sum;
}

int main(){
    char ch;
    string digit = "";
    int sum = 0;
    while(scanf("%c", &ch) != EOF ){
	if ( '0' <= ch && ch <= '9' ) digit += ch;
	else {
	    if ( digit.size() > 0 ) sum += getInt(digit);
	    digit = "";
	}
    }

    cout << sum << endl;
    return 0;
}
```
