    scanf("%d", &n);
    while(n != 1){
        if(n%2 == 0){
            n = n/2;
        }
        else{
            n = (3*n + 1)/2;
        }

    scanf("%d
",&num);
    while(num--){
        long long a,b,c;
        scanf("%lld%lld%lld",&a,&b,&c);
        if(a+b>c){
            printf("Case #%d: true
",sec++);
        }else{
            printf("Case #%d: false
