### Prompt

Please provide a Cpp coded solution to the problem described below:

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 buf;
	int num = 0;
	while ( getline(cin, buf) ) {
		int tmp_num = 0;
		bool num_mode = false;
		while ( !buf.empty() ) {
			if ( '0' <= buf[0] && buf[0] <= '9' ) {
				tmp_num *= 10; tmp_num += buf[0] - '0';
				num_mode = true;
			}
			else if (num_mode) {
				num += tmp_num; tmp_num = 0;
				num_mode = false;
			}
			buf.erase( buf.begin() );
		}
		num += tmp_num;
	}
	
	cout << num << endl;
	
	return 0;
}
