### Prompt

Your challenge is to write 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

Output

123

### Response

```cpp
#include<iostream>
#include<string>
#include<sstream>
#include<utility>
using namespace std;
pair<int,string> f(string s){
stringstream ss(s);
int n;string res;
ss>>n>>res;
return make_pair(n,res);
}
int main(){
string s;
int ans = 0;
while(cin>>s){
while(true){
while((s[0]<'0'||'9'<s[0]) && s.size()!=0)s=s.substr(1);
if(s.size()==0)break;
pair<int,string> tmp;
tmp= f(s);
ans += tmp.first;
s = tmp.second;
}
}
cout<<ans<<endl;
}
```
