## What is Fizzbuzz?

- A common interview question engineers see.
- In this example we want to show a number divisible by 3, 5, or 3 and 5 returns a string.
- 3 returns fizz.
- 5 returns buzz.
- 3 and 5 returns fizzbuzz.

## Solution

```
def fizzbuzz(number)
i = 1
until i > number
if i % 15 == 0
puts "#{i} is divisible by 3 and 5 so return fizzbuzz"
elsif i % 3 == 0
puts "#{i} is only divisible by 3 so return fizz"
elsif i % 5 == 0
puts "#{i} is only divisible by 5 so return buzz"
end
i += 1
end
end
```

- Create a method that accepts an argument that will be a number.
- Set a variable to 1 so as you iterate you have a starting point.
- Setup an
`until`

loop where it will run until `i`

is greater than the number given in the argument. - We then create an
`elsif`

statement where it will check if `i`

is divisible by 15, 3, and 5.- Using
`if`

and `elsif`

will only return the values that match.

- We also place the check if something is divisbile by 3 and 5 first because if we put it last one of the other conditions will be met first and would print out something we don’t expect.

- Use
`%`

operator (Modulus) which divides the left side by the right side and returns the remainder. We then check if the answer is 0 to ensure we get only numbers that divide cleanly. - If the
`if`

or `elsif`

condition is met print out the string. - Finally we want to continue to add to
`i`

until it reaches greater than the `number`

argument so using `+=`

syntax tells ruby to add 1 to `i`

.
