### 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 <bits/stdc++.h>
#define rep(i,l,n) for(int i=l;i<n;i++)
#define all(a) a.begin(),a.end()
#define o(a) cout<<a<<endl
using namespace std;

int main(){
	int ans=0;
	string s;
	while(cin>>s){
		rep(i,0,s.size()){
			if(s[i]-'0'>=0 && s[i]-'0'<10){
				rep(j,i,s.size()){
					if(s[j]-'0'<0 || s[j]-'0'>=10 || j == s.size() - 1){
						if(j==s.size()-1) j++;
						ans+=atoi(s.substr(i,j-i).c_str());
						//cout<<atoi(s.substr(i,j-i).c_str())<<endl;
						i = j;
						break;
					}
				}
			}
		}
	}
	o(ans);
}
