### Prompt

Please formulate 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>

int main(){
	int sum = 0;
	int temp = 0;
	char c;
	while(~scanf("%c",&c)){
		if('0' <= c && c <= '9'){
			temp *= 10;
			temp += c - '0';
		}else{
			sum += temp;
			temp = 0;
		}
	}
	sum += temp;
	printf("%d\n", sum);
}
```
