### 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

### Response

```cpp
#include <stdio.h>
#include <string.h>

int main(void)
{
	int i, j;
	int n;
	int num;
	char str[128];
	int ans;
	int len;
	
	ans = 0;
	while (fgets(str, 100, stdin) != NULL){
		n = 0;
		len = strlen(str);
		for (i = 0; i < len; i++){
			if (str[i] >= '0' && str[i] <= '9'){
				n++;
			}
			else {
				num = 0;
				for (j = 0; j < n; j++){
					num *= 10;
					num += str[i - n + j] - '0';
				}
				n = 0;
				ans += num;
			}
		}
	}
	printf("%d\n", ans);
	
	return (0);
