### Prompt

Develop a solution in cpp to the problem described below:

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 <sstream>
using namespace std;

int main(){
  string str;
  int sum = 0,num;

  while(getline(cin,str)){
    for(int i = 0 ; i < str.size() ; i++){
      if('0' <= str[i] && str[i] <= '9') continue;
      else str[i] = ' ';
    }

    stringstream s;
    s << str;
    while(s >> num){
      sum += num;
    }
  }
  cout << sum << endl;

  return 0;
}
