### 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<string>
using namespace std;

int main(){

  string s;
  int ans = 0;

  while(cin >> s){

    for(int i=0;i<s.size();i++){

      int z = 0;

      while(s[i] >= '0' && s[i] <= '9'){
	z *= 10;
	z += s[i] - '0';
	i++;
      }

      ans += z;
    }
  }

  cout << ans << endl;
}
```
