### 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>

int main(int argc, const char * argv[]) {
    char basicstr[80];
     int sum = 0;
    
    while(scanf("%s",basicstr) != EOF){
        int x  = 0;
        for(int i = 0;basicstr[i];i++){
            if(isdigit(basicstr[i])){
                x = x * 10 + (basicstr[i] - '0');
            }else{
                sum += x;
                x = 0;
            }
        }
        sum += x;
    }
    
    printf("%d\n",sum);
    return (0);
}
