### Prompt

Please create a solution in cpp 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;
int main()
{
    int ans = 0;
    char str[100];
    while (cin >> str)
    {
        int len = strlen(str);
        for (int i = 0; i < len; i++)
        {
            int n = 0;
            while (str[i] != '\0' && isdigit(str[i]))
            {
                n = n*10 + str[i++] - '0';
            }
            ans += n;
        }
    }
    printf("%d\n", ans);
    return 0;
