Hello , Ruby!

Question

Write a program that outputs the string representation of numbers from 1 to n.
But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and five output “FizzBuzz”.

Answer

程序中主要使用了

• for i in start .. end循环结构，也可以用 times,while实现
• if then else 选择结构
• % 求余运算
• and 与逻辑运算
• 数组
• 方法定义：def function_name(args,…) … end

# @param {Integer} n
# @return {String[]}
def fizz_buzz(n)
    result = Array.new()
    for i in 1 .. n
        if i % 3 == 0 and i % 5==0 then
          result
