### Prompt

Create a solution in cpp for 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>

typedef string::const_iterator State;

int parse(State &it){
  int ret = 0;
  while(isdigit(*it)){
    ret = ret * 10;
    ret = ret + *it - '0';
    it++;
  }
  return ret;
}

int main(void){
  int sum = 0;
  while(cin >> sentence){
    for(State it = sentence.begin(); it != sentence.end(); it++){
      if(isdigit(*it)){
        sum += parse(it);
        it--;
      }
    }
  }
  cout << sum <<endl;
  return 0;
