### Prompt

Develop a solution in CPP 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>
int main()
{
	int ans = 0;
	for (std::string str; std::getline(std::cin, str);)
	{
		int sum = 0;
		for (auto i : str)
		{
			if ('0' <= i && i <= '9')
			{
				sum *= 10;
				sum += static_cast<int>(i - '0');
			}
			else
			{
				ans += sum;
				sum = 0;
			}
		}
		ans += sum;
	}
	std::cout << ans << std::endl;
	return 0;
}

```
