### 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>

using namespace std;
/** Problem0064 : Secret Number **/
int main()
{
	string s;
	int ans=0, tmp;
	
	while (cin >> s) {
		int len = (int)s.length();
		tmp = 0;
		for (int i=0; i<len; i++) {
			if ('0' <= s[i] && s[i] <= '9') {
				if (tmp>0) {
					tmp*=10; tmp+=s[i]-'0';
				} else
					tmp+=s[i]-'0';
			} else {
				ans+=tmp;
				tmp=0;
			}
		}
		ans += tmp;
	}
	cout << ans << endl;
	
	return 0;
}
