### Prompt

Your task is to create 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<string>
using namespace std;
int main(){
	int count=0;
	string a;
	while(cin>>a){
		int i=a.size()-1;
		int e=1;
		while(true){
			if(a[i]>='0'&&a[i]<='9'){
				count+=e*(a[i]-'0');
				e*=10;
			}
			else
				e=1;
			if(i==0)
				break;
			i--;
		}
	}
	cout<<count<<endl;
	return 0;
}
