### 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 <bits/stdc++.h>
using namespace std;

#define rep(i,n) for(int i=0;i<(n);++i)
#define loop for(;;)
#define trace(var) cerr<<">>> "<<#var<<" = "<<var<<endl;
#define inf (1e9)
#define eps (1e-9)

int main() {
  string s;
  int ans = 0;
  while (getline(cin, s)) {
    transform(begin(s), end(s), begin(s), [](char c){ return isdigit(c) ? c : ' '; });
    stringstream ss(s);
    int x;
    while (ss >> x) ans += x;
  }
  cout << ans << endl;

  return 0;
}
