### Prompt

In cpp, your task is to solve 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 <cstdio>

using namespace std;

char c;
string s;
int ans,size,a,n;

int get_int(){

  size = s.size();
  a = 1;
  n = 0;
  for( int i = size - 1 ; i >= 0 ; i-- ){
    n += ( s[i] - '0' ) * a;
    a *= 10;
  }
  return n;
}

int main(void){

  s = "";
  ans = 0;

  while( scanf("%c",&c) != EOF ){
    if( '0' <= c && c <= '9' ){
      s += c;
    }
    else {
      ans += get_int();
      s = "";
    }
  }
  cout << ans << endl;
  return 0;
}
