### Prompt

In Cpp, your task is to solve 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>
using namespace std;

int main()
{
	char str;
	int ans = 0, save = 0,  x = true;
	
	while (scanf("%c", &str) != EOF){
		if (str >= '0' && '9' >= str){
			if (!x){
				save *= 10;
			}
			save += str - '0';
			x = false;
			//printf("[%d]", ans);
		}
		else {
			ans += save;
			save = 0;
			x = true;
		}
	}
	
	printf("%d\n", ans);
}
```
