### 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 <cstring>
using namespace std;

int main(void)
{
	unsigned long long res = 0, num = 0;
	char str[128];
	bool flag = true;
	
	while (scanf("%s", str) != EOF){
		int len = strlen(str);
		for (int i = 0; i < len; i++){
			if ('0' <= str[i] && str[i] <= '9'){
				for (int j = i; j < len; j++){
					if ('0' <= str[i] && str[i] <= '9') {
						num *= 10;
						num += str[i] - '0';
						i++;
					}
					else break;
				}
			}
			res += num;
			num = 0;
		}
	}
	
	printf("%llu\n", res);
	
	return (0);
