### 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.
Ishouldgohomeat6pm.


Output

123

### Response

```cpp
#include <iostream>
#include <string>

using namespace std;

int main(){
    int ans = 0;
    int tmp = 0;
    string str;
    while(cin >> str){
	tmp = 0;
	for(int i=0;i<str.size();i++){
	    if('0'<=str[i] && str[i] <='9'){
		tmp += str[i] -'0';
	    }
	    if(i+1 == str.size() || '0' > str[i+1] || str[i+1] > '9'){
		ans += tmp;
		tmp = 0;
	    }
	    else{
		tmp *= 10;
	    }
	}
    }
    cout << ans << endl;
    return 0;
}
