### Prompt

Please formulate 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 ans=0;
    while(cin>>str){
        for(int i=0;;i++){
            if(str[i]==0)break;
            if(str[i]>'0'&&str[i]<='9'){
                int j;
                for(j=i;str[j]>='0'&&str[j]<='9';j++){};
                int a=j-i;
                j--;
                int r=1;
                while(a--){
                    ans+=(str[a+i]-'0')*r,r*=10;
                }
                i=j;
            }
