int a;
int c;
cin>>i>>a>>c;
char fat=i%2;
char cat=a%2;
char car=c%2;
if(fat==0&&cat==0&&car==0){
cout<<i+a+c;
}
else if(fat>=1&&cat==0&&car==0){
cout<<a+c;
}
else if(fat==0&&cat>=1&&car==0){
cout<<i+c;
}
else if(fat==0&&cat==0&&car>=1){
cout<<i+a;
}
else if(fat>=1&&cat==0&&car>=1){
cout<<a;
}
else if(fat>=1&&cat>=1&&car==0){
cout<<c;
}else if(fat==0&&cat>=1&&car>=1){
cout<<a;}
else if(cat=='\0'){
for(i=0;i>=cat;--i){
int c=i;
if(c%2==0){
cout<<"0";
}
}}
return 0;
}
