There's an error in the readme of the fizz buzz algorithm found here: https://github.com/raywenderlich/swift-algorithm-club/tree/master/Fizz%20Buzz
A table giving example results of using the modulus operator shows that 1/3 results in 0 with a remainder of 3. This should however be 0 with a remainder of 1. and thus the modulus result in the last column of the table should also be 1 instead of 3.
