int flag;
for(i=1;i<n;i++){
flag=0;
if (i % 3 ==0) flag=1;
if (i % 5 ==0) flag+=2;
switch (flag){
case 0:
System.out.println(i);
break
case 1:
System.out.println("Fizz");
break;
case 2:
System.out.println("Buzz");
break;
case 3:
System.out.println("FizzBuzz");
break;
}
}
這樣會不會快一點點,使用int當flag,效能會略好,每個bit代表一種可能,
32 bit,可以有32種可能,後續擴充性較好,每個人習慣不同,謝謝大家指教了
