### 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 <iostream>
#include <cstring>
#include <cstdlib>
using namespace std;
int main()
{
	int i, r = 0, t = 1;
	char s[81] = "", c;
	while (cin >> s)
	{
		for (i = strlen(s); i >= 0; i--)
		{
			c = s[i];
			if ('0' <= c && c <= '9')
			{
				r += atoi(&c) * t;
				t *= 10;
			}
			else
			{
				t = 1;
