### 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.

Output

123

```cpp

#include<string.h>

int main(void)
{
	const int N = 80;
	char str[N+1];
	int count = 0;
	while(scanf("%s", str) == 1)
	{
		const char* p = str;
		while( (p = strpbrk(p, "0123456789")) != 0)
		{
			char* nextp;
			int next;
			count += (next = strtol(p, &nextp, 10));
			if(next == 0)
				break;
			p = nextp;
		}
	}
	printf("%d\n", count);
	return 0;
