### 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 <stdio.h>
#include<math.h>
#include <algorithm>
using namespace std;

int main(){
	char buf[81];
	int sum = 0,tmp;

	while(scanf("%s",buf)!=EOF){
		tmp = 0;
		for(int i=0;buf[i] != '\0';i++){
			if(buf[i] >= 48 && buf[i] <= 57){
				tmp = 10*tmp + (buf[i] - '0');
				if(buf[i+1] == '\0'){
					sum += tmp;
				}
			}else{
				if(buf[i-1] >= 48 && buf[i-1] <= 57){
					sum += tmp;
					tmp = 0;
				}
			}
		}
	}

	printf("%d\n",sum);

    return 0;
}
