### 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>

using namespace std;

int main(void){
    int i;
    int sum=0;
    int sum_t=0,len;
    char str[81];

        len=strlen(str)+1;
        for(i=0;i<len;i++){
            if('0'<=str[i]&&str[i]<='9'){
                sum_t*=10;
                sum_t+=str[i]-'0';
            }else{
                sum+=sum_t;
                sum_t=0;
