### 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.

Output

123

### Response

```cpp
#include<iostream>
#include<string>
#include<vector>
#include<map>
using namespace std;

int main(void){
  string s;
  int res = 0, n = 0;
  while(getline(cin,s)){
    for(int i = 0 ; i < s.size() ; i ++){
      if('0' <= s[i] && s[i] <= '9'){
	n = n * 10 + s[i] - '0';
      }else{
	res += n;
	n = 0;
      }
    }
  }
  cout<<res<<endl;
}
