### Prompt

Construct a Cpp code solution to the problem outlined:

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<cstdlib>
using namespace std;

int main() {
	string sentence; string num_tmp; int num=0;
	while(cin>>sentence) {
		num_tmp = "";
		for (int i = 0; i < sentence.size(); i++) {
			if (47 < sentence[i] &&sentence[i]< 58) {
				num_tmp += sentence[i];
			}
			else {
				num += atoi(num_tmp.c_str());
				num_tmp = "";
			}
		}
		num += atoi(num_tmp.c_str());
	}
	cout << num << endl;
