### 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>
#define rep(i,a) for(int i = 0 ; i < a ; i ++)

using namespace std;

int main(void){
  string str;
  int sum=0;
  while(cin>>str){
    int next=0;
    rep(i,str.size()){
      if('0'<=str[i]&&str[i]<='9'){
	if('0'<=str[i+1]&&str[i+1]<='9'){
	  next = next * 10 + (str[i] - '0') ;
	  //	  cout<<next<<" "<<str[i]<<endl;
	}else if('0'<=str[i-1]&&str[i-1]<='9' || !('0'<=str[i+1]&&str[i+1]<='9')){
	  
	  //	  cout<<next*10+str[i]-'0'<<endl;
	  sum+=next*10+str[i]-'0';next=0;
	}
      }
    }

  }
  cout<<sum<<endl;
}
