### 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

Output

### Response

```cpp
#include <cstdio>
#include <cstdlib>
#include <cctype>
#include <cstring>
int main()
{
	char buf[128];
	int res = 0;
	while (fgets(buf, 128, stdin)) {
		for (int i = 0; buf[i]; ++i) if (!isdigit(buf[i])) buf[i] = ' ';
		char* p = strtok(buf, " ");
		while (p) { res += atoi(p); p = strtok(NULL, " "); }
	}
	printf("%d\n", res);
	return 0;
}
