### Prompt

Generate 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>

using namespace std;

int main(){

  string in;
  int sum = 0;
  while(getline(cin,in)){
    int kake = 1;
    for(int i = in.length()-1; i >= 0; i--){
      if(in[i] < '0' || in[i] > '9'){
	kake = 1;
	continue;
      }
      sum += (in[i] - '0') * kake;
      kake *= 10;
    }
  }
  cout << sum << endl;
  return 0;
}
