### Prompt

Develop a solution in CPP to the problem described below:

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 <bits/stdc++.h>
using namespace std;

const int INF = 1e+9;

int main() {
	string s;
	int ans = 0;
	while(cin >> s){
		int res = 0, cnt = 0, sum = 0;
		for(int i = 0; i < s.size(); ++i){
			if('0' <= s[i] && s[i] <= '9'){
				if(cnt != 0)
					sum *= 10;
				sum += s[i] - '0';
				cnt++;
			}
			else{
				res += sum;
				cnt = 0;
				sum = 0;
			}
		}
		res += sum;
		ans += res;
	}
	cout << ans << endl;
	return 0;
}
```
