### Prompt

Your task is to create 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 <stdio.h>
#include <string.h>

int main(void){
	char str[100];
	int num;
	int code = 0;

	scanf("%d", &num);
	while(scanf("%s", str) != EOF){
		int len = strlen(str);
		for(int i=0; i<len; i++){
			if(str[i] >= '0' && str[i] <= '9'){
				int temp = i;
				while(str[i] != '\0' && str[i] >= '0' && str[i] <= '9'){
					i++;
				}
				str[i] = '\0';
				sscanf(&str[temp], "%d", &num);
				code += num;
			}
		}
	}
	printf("%d\n", code);

	return 0;
}
```
