C :

#include <stdio.h>
int main()
{
    int a,b,c,d;
    while(scanf("%d%d%d",&a,&b,&c)!=EOF)
    {
        if(a%3==0)a=0;
        if(b%5==0)b=0;
        if(c%7==0)c=0;
        for(d=10;d<=100;d++)
        {
            if(d%3==a&&d%5==b&&d%7==c){printf("%d\n",d);break;}
        }
        if(d%3!=a||d%5!=b||d%7!=c){printf("No answer\n");}
    }
    return 0;
}

C++ :

#include<iostream>
using namespace std;
int main()
{
	int a,b,c;
	while(cin>>a>>b>>c)
    {

	int n=(a*70+b*21+c*15)%105;
	if(n>100||n<10) cout<<"No answer"<<endl;
	else cout<<n<<endl;
    }
    return 0 ;
}

Pascal :

var a,b,c,i,n:longint;
begin
  read(a,b,c);
  for i:=10 to 100 do
    if (i mod 3=a) and  (i mod 5=b) and (i mod 7=c) then
    begin
      writeln(i);
      exit;
    end;
  writeln('No answer');
end.
