### Prompt

In cpp, your task is to solve 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<cstdio>
#include<cstring>
#include<cctype>
using namespace std;
const int MAX_STR=80;
int main(){
	int res=0;
	char s[MAX_STR+1];
	while(cin>>s){
		for(int i=0;i<strlen(s);i++){
			if(isdigit(s[i])){
				int t=0;
				for(;i<strlen(s)&&isdigit(s[i]);i++){
					t*=10;
					t+=s[i]-'0';
				}
				res+=t;
			}
		}
	}
	cout<<res<<endl;
	return 0;
}
