### 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 <iostream>
#include <string>
#include <cctype>
using namespace std;

int main(int argc, const char * argv[])
{
    int snum = 0;
    int stuck = 0;
    string slit;
    while(cin >> slit){
        for (int i = 0; i < (int)slit.length(); i++) {
            if (isdigit(slit[i])) {
                stuck *= 10;
                stuck += slit[i] - '0';
            }
            if (!isdigit(slit[i + 1])) {
                snum += stuck;
                stuck = 0;
            }
        }
    }
    cout << snum << endl;
    return 0;
}
