### Prompt

In Cpp, your task is to solve 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 <string>
#include <cstdlib>

using namespace std;

int main(){

	string s;
	int sum=0;
	while(cin>>s){
		for(int i = 0; i < s.size(); i++){
			if(s[i]>='0'&&s[i]<='9'){
				int j = i+1;
				while(1){
					if(s[j]>='0'&&s[j]<='9'){
						j++;
					}
					else
						break;
				}
				sum+=atoi(s.substr(i,j-i).c_str());
				i=j-1;
			}
		}
	}
	cout<<sum<<endl;
	return 0;
}
