### 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>
#include <string>
using namespace std;

int main() {

  string input;
  int ans = 0;
  int cnt = 0;

  while( getline( cin, input ) ) {
    ans += cnt;
    cnt = 0;
    for ( int i = 0; i < input.size(); i++ ) {
      if ( input[i] >= '0' && input[i] <= '9' ) {
	cnt = cnt*10 + input[i] - '0';
      }else {
	ans += cnt;
	cnt = 0;
      }
    }
  }

  ans += cnt;

  cout << ans << endl;

  return 0;

}
