### 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>
#include<cstdlib>
#include<cctype>

int main()
{
	std::string s;
	int ans = 0;
	while( std::cin >> s )
	{
		int i = 0;
		while( i < s.size() )
		{
			int j = i;
			while( isdigit( s[j] ) )
				++j;

			if( i != j )
			{
				ans += atoi( s.substr( i, j - i ).c_str() );
				i = j;
			}

			++i;
		}
	}

	std::cout << ans << std::endl;

	return 0;
}
```
