### 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<cstdlib>
#include<string>
using namespace std;
int main() {
	string a;
	int sum = 0;
	while (getline(cin, a)) {
		for (int i = 0; i < a.length(); i++) {
			if (a[i] >= '0'&&a[i] <= '9') {
				string h = "";
				while (a[i] >= '0'&&a[i] <= '9') {
					h += a[i];
					i++;
				}
				int s = atoi(h.c_str());
				sum += s;
			}
		}
	}
	cout << sum << endl;
}
