### Prompt

Please provide a CPP coded solution 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<cmath>
using namespace std;

int main(){

	int n, len, cnt;
	string str;
	
	n = 0;
	while(getline(cin, str)){
		len = str.length();
		cnt = 0;
		for(int i=len-1; i>=0; i--){
			if(str[i] >= '0' && str[i] <= '9'){
				n += (str[i] - '0') * pow(10, cnt);
				cnt++;
			}
			else {
				cnt = 0;
			}
		}
	}

	cout << n << endl;

	return 0;
