### Prompt

Your task is to create 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<cstdio>
//#include<stdlib.h>
using namespace std;

int main(){
  int n=0,sum=0;
  char c;
  while(1){
    if(scanf("%c",&c)==EOF){
      sum += n;//
      break;
    }
    if('0' <=c && c <= '9'){
      n *= 10;//
      //    n += atoi(c);
      n += c -'0';//'0'=48charc48//
    }
    else{
      sum += n;n=0;
    }
  }
  cout << sum << endl;
  

  return 0;
}
