### 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

Thereare100yenonthetable.Iam17yearsold.
Ishouldgohomeat6pm.


Output

123

### Response

```cpp
#include <iostream>
#include <string>
using namespace std;

int main(){
	string str;
	int count = 0;
	while(cin >> str){
		int tmp = 0;
		for(int i = 0; i <= (int)str.size(); i++){
			if('0' <= str[i] && str[i] <= '9'){
				tmp = tmp * 10 + str[i] - '0';
			}else{
				count += tmp;
				tmp = 0;
			}
		}
	}
	cout << count << endl;
	return 0;
}

```
