### Prompt

Construct a cpp code solution to the problem outlined:

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 <math.h>
using namespace std;

int main()
{
	string str;
	int ans = 0;

	while (getline(cin, str))
	{
		int j = 0;
		for (int i = str.size() - 1; i >= 0; i--)
		{
			if ('0' <= str[i] && str[i] <= '9')
			{
				ans += pow(10, j) * (str[i] - '0');
				j++;
			}
			else
			{
				j = 0;
			}
		}
	}
	cout << ans << endl;

	return 0;
