### 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>
#include <string>
#include <stdlib.h>
using namespace std;

int main() {
  string memo;
  int num, temp;

  num = 0;
  while(cin >> memo) {
    temp = 0;
    for(int i = 0; i <= (int)memo.size(); i++){
      if(memo[i] - '0' >= 0 && memo[i] - '0' <= 10) {
        temp = temp * 10;
        temp += (memo[i] - '0');
      }
      else {
        num += temp;
        temp = 0;
      } 
    }   
  num += temp;
  }

  cout << num << endl;

  return 0;
}
