### Prompt

Please provide a cpp coded solution to the problem described below:

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 str;
  const char *p;
  int res = 0;
  
  while(cin >> str) {
    p = &str[0];
    for(; p-&str[0]<(int)str.size(); p++) {
      if(isdigit(*p)) {
	char *e;
	int a;
	a = strtol( p, &e, 10 );
	p = e;
	res += a;
      }
    }
  }
  
  cout << res << endl;
  
  return 0;
