### Prompt

Please create a solution in Cpp 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

```cpp

	}
	return tmp;
}
int main()

	string str; int sum=0;
	while(cin>>str)
	{
		for(int s=0,l=0;s<str.size();s=++l)
		{
			if(str[l]-'0'<0 || str[l]-'9'>0) continue;
			while(l+1<str.size() && str[l+1]-'0'>=0 && str[l+1]-'9'<=0) l++;
			string ss=str.substr(s,l-s+1);
			sum+=chtoi(ss);
