### 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 <iostream>
#include <string>

using namespace std;

void solve()
{
	int sum = 0;
	string str;
	while(getline(cin, str))
	{
		int size = str.size();
		
		for(int i = 0; i < size; ++i)
		{
			if('0' <= str[i] && str[i] <= '9')
			{
				string temp;
				while('0' <= str[i] && str[i] <= '9')
				{
					temp += str[i];
					++i;
				}
				int size2 = temp.size();
				int a = 1;
				for(int j = size2 - 1; j >= 0; --j)
				{
					sum += (temp[j] - '0') * a;
					a *= 10;
				}
			}
		}
	}
	cout << sum << endl;
}

int main()
{
	solve();
	return(0);
}
