### 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 <iostream>
using namespace std;

int main()
{
	char str[1000];
	int se = 0, dig = 1, dignum;

	while (cin >> str){
		for (int i = 0; str[i] != '\0'; i++){
			if (str[i] <= '9' && str[i] >= '0'){
				dignum *= 10;
				dignum += str[i] - '0';
			}	
			if (!(str[i] <= '9' && str[i] >= '0') || (str[i] <= '9' && str[i] >= 0) && str[i + 1] == '\0'){
				se += dignum;
				dignum = 0;
			}
		}
	}
		cout << se << endl;

		return (0);
}
