### Prompt

Please provide a Cpp coded solution 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 <stdio.h>
#include <string.h>
int main(){
char x;
int sum=0,y=0,ans=0,i,z;
while(scanf("%c",&x)!=EOF){
z=x-'0';
if(z>=0 && z<=9){
if(y==0){sum*=10;}sum+=z;y=0;
}else{y=1; ans+=sum; sum=0;}
}
if(sum!=0){
	ans+=sum;}
printf("%d\n",ans);
return 0;
