### 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 <iostream>
#include <string>
#include <cstdlib>
using namespace std;

int main(){
	string s,a;
	int n = 0;
	while(getline(cin,s)){
		for(int i = 0;i < s.length();++i){
			if('0' <= s[i] && s[i] <= '9' && i < s.length()){
				a = s[i];
				++i;
				while('0' <= s[i] && s[i] <= '9' && i < s.length()){
					a += s[i];
					++i;
				}
				n += atoi(a.c_str());
			}
		}
	}
	cout << n << endl;
	return 0;
}
