### Prompt

Your challenge is to write 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<stdio.h>
#include<string.h>
#include<math.h>

int main(){
	char ss[90];
	int i,j,number,k,t;
	number=0;
	while(~scanf(" %s ",ss)){
		for(i=0;;i++){
			if(ss[i]=='\0')break;
			
			if(ss[i]>'0' && ss[i]<='9'){
				t=i;
				for(j=i;;j++){
					if(ss[j]<'0' || ss[j]>'9')break;
				}
				--j;
				t=j;
				k=1;
				for(j;j>=i;j--){
					number+=(ss[j]-'0')*k;
					k*=10;
				}
				i=t;
			}
		}
	}
	
	printf("%d\n",number);
}
