### Prompt

Generate 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 <cstdio>
#include <ctype.h>

using namespace std;

int main(void){
	int sum = 0, val;
	char c;
	while((c = getchar()) != EOF){
		if(isdigit(c)){
			val = c - '0';
			while(isdigit(c = getchar())){
				val = val * 10 + c - '0';
			}
			sum += val;
		}
	}
	printf("%d\n",sum);
	return 0;
