### 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

Thereare100yenonthetable.Iam17yearsold.
Ishouldgohomeat6pm.


Output

123

### Response

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

int main(){
  int i,sum,k;
  string s;
  i=0;
  sum=0;
  while(cin>>s){
    
    k=1;
    for(int j=s.size()-1;j>=0;j--){
      if('0'<=s[j]&&s[j]<='9'){
	sum+=k*(s[j]-'0');
	k*=10;
      }else k=1;
    }
    
  }
  cout<<sum<<endl;
    return 0;
}
```
