### Prompt

Create a solution in cpp for 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

```cpp
#include <cstdio>

      if('0' <= str[i] && str[i] <= '9'){
	n += str[i] - '0';
	if(str[i+1] != '\0' && '0' <= str[i+1] && str[i+1] <= '9'){
	  n *= 10;
	}
	else if(str[i+1] == '\0' || '0' > str[i+1] || str[i+1] > '9'){
	  ans += n;
	  n = 0;
	}
      }
    }
