### Prompt

Generate a Cpp solution 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

### Response

```cpp
#include <iostream>
#include <cstring>
using namespace std;

int main(){
	string str;
	int ans;
	int num;
	
	ans = 0;
	while(cin >> str){
		for(int i = 0; i < str.size(); i++){
			num = 0;
			while(str[i] >= 48 && str[i] <= 57 && i < str.size()){
				num *= 10;
				num += str[i] - 48;
				i++;
			}
			ans += num;
		}
	}
	
	cout << ans << endl;
	
	return 0;
}
