### Prompt

Develop a solution in CPP 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>
using namespace std;

int main(void) {
	string str;
	int start, end, x;
	int sum = 0;
	
	while(cin >> str) {
		int i = 0;
		while(i < str.length()) {
			if('0' <= str[i] && str[i] <= '9') {
				start = i;
				while('0' <= str[i] && str[i] <= '9') {
					end = i;
					++i;
				}
				x = 1;
				for(int j = end; j >= start; --j) {
					sum += (str[j] - '0') * x;
					x *= 10;
				}
			}
			++i;
		}
	}
	
	cout << sum << endl;
	
	return 0;
}
