### Prompt

In CPP, your task is to solve 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 <string>
#include <iostream>

using namespace std;

int main()
{
	int ret = 0;
	
	string S;

	while (cin >> S)
	{
		int sum = 0;

		for (int i = 0; i < S.size(); i++)
		{
			if (!isdigit(S[i]))
			{
				ret += sum; sum = 0;
			}
			else
			{
				sum *= 10; sum += S[i] - 48;
			}
		}

		ret += sum;
	}

	cout << ret << endl;

	return 0;
}
```
