### 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<bits/stdc++.h>

using namespace std;

int main()
{
  int sum = 0;
  string s;

  while(cin>>s){
    int check = 0;
    int temp = 0;
    
    for(int i = 0; i < s.size();++i){
      if(!isdigit(s[i])){
        check = 0;
      }
      else{
        if(check == 0){
          temp += s[i] - 48;
          check = 1;
        }
        else{
          temp = temp * 10;
          temp += s[i] - 48;
        }
      }

      if(check == 0 || i == s.size() - 1){
        sum += temp;
        temp = 0;
      }
    }
  }
  cout<<sum<<endl;
