### Prompt

Develop a solution in cpp 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(){
  string str;
  int ans=0;
  while(getline(cin,str)){
    int len = str.size();
    string numstr="";
    bool flag=false;
    for(int i=0;i<len;i++){
      if(str[i]>='0' && str[i]<='9'){
	numstr += str[i];
	flag = true;
      }
      else if(flag){
	flag = false;
	istringstream iss(numstr);
	int num=0;
	iss >> num;
	ans += num;
	numstr = "";
      }
    }
    istringstream iss(numstr);
    int num=0;
    iss >> num;
    ans += num;
    numstr = "";
  }
  cout << ans << endl;
}
