为什么我的"Fizz Buzz"没有显示测试在R工作? [英] Why isn't my "Fizz Buzz" test in R working?

问题描述

我听说这是一个常见的面试问题，有什么想法吗，谢谢.

I heard this was a common interview question, any ideas what is off here, thank you.

for(i in 1:100){
  if(i%15==0){
    print('fizzbuzz')
  } else 
      if (i%3==0){
        print("fizz")
      } else 
        if (i%5==0) {
          print("buzz")
        } else 
          (print(i))
        }
      }

推荐答案

我将花括号放在不同的位置，您需要更正运算符-%%而不是%.

I'd place the curly braces in different spots, and you need to correct the operator -- %% instead of %.

for(i in 1:100) {
    if(i%%15==0){
        print('fizzbuzz')
    } else if (i%%3==0){
        print("fizz")
    } else if (i%%5==0) {
        print("buzz")
    } else {
        print(i)
    }
} 

但是基本思想是合理的:首先清除特殊的"fizzbuzz"案例，然后再处理其余(专有)案例.

But the basic idea is sound: get the special 'fizzbuzz' case out the way first, then deal with remaining (exclusive) cases.

以下是前16个结果:

edd@max:~$ r /tmp/fizzbuzz.R | head -16
[1] 1
[1] 2
[1] "fizz"
[1] 4
[1] "buzz"
[1] "fizz"
[1] 7
[1] 8
[1] "fizz"
[1] "buzz"
[1] 11
[1] "fizz"
[1] 13
[1] 14
[1] "fizzbuzz"
[1] 16
edd@max:~$
