### Prompt

Your challenge is to write 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

		int x = 0;
		for (int i = 0; s[i]; i++){
			if (isdigit(s[i])){
				x = x * 10 + (s[i] - '0');
			}
			else {
				sum += x;
				x = 0;
			}
		}
		sum += x;
	}
	
	printf("%d\n", sum);
	
	return(0);
