### Prompt

Your task is to create a CPP solution to 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<string>
using namespace std;
int main(){
  string str;
  int cnt=0;
  while(cin>>str){
    int cc=0;
    for(int i=0;i<str.size();i++){
      string str2="";
      while(str[i+cc]>='0'&&str[i+cc]<='9'){
	cc++;
	//	cout<<"!"<<endl;
      }
      //cout<<str2<<endl;
      str2=str.substr(i,cc);
      for(int k=str2.size()-1;k>=0;k--){
	int hiseki=1;
	for(int j=0;j<str2.size()-k-1;j++)
	  hiseki*=10;
	cnt+=(str2[k]-'0')*hiseki;
      }
      i+=cc;
      cc=0;
    }
  }
  cout<<cnt<<endl;
  return 0;
}
