|Getting Started with Simple Fizz Buzz Algorithm in Swift – Algorithms Code|
For those of you that are new to programming in Swift and those of you coming from different programming bases, such as Python or Java, this article should be quite helpful. In this post, we will discuss a simple solution for implementing swift algorithms.
You may have seen Fizz Buzz written as Fizz Buzz, FizzBuzz, or Fizz-Buzz; they’re all referring to the same thing. That “thing” is the main topic of discussion today. First, what is FizzBuzz?
This is a common question that comes up in job interviews. Imagine a series of a number from 1 to 10.
Fizz and Buzz refer to any number that’s a multiple of 3 and 5 respectively. In other words, if a number is divisible by 3, it is substituted with fizz; if a number is divisible by 5, it is substituted with buzz. If a number is simultaneously a multiple of 3 AND 5, the number is replaced with “fizz buzz.” In essence, it emulates the famous children game “fizz buzz”.
To work on this problem, open up Xcode to create a new playground and initialize an array like below:
// for example
// here 3 is fizz and 5 is buzz
To find all the fizz and buzz, we must iterate through the array and check which numbers are fizz and which are buzz. To do this, create a for loop to iterate through the array we have initialised:
After this, we can simply use the “if else” condition and module operator in swift ie – % to locate the fizz and buzz
Great! You can go to the debug console in Xcode playground to see the output. You will find that the “fizzes” have been sorted out in your array.
For the Buzz part, we will use the same technique. Let’s give it a try before scrolling through the article — you can check your results against this article once you’ve finished doing this.
Check the output!
It’s rather straight forward — you divided the number by 3, fizz and divided the number by 5, buzz. Now, increase the numbers in the array
let number = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]
We increased the range of numbers from 1-10 to 1-15 in order to demonstrate the concept of a “fizz buzz.” Since 15 is a multiple of both 3 and 5, the number should be replaced with “fizz buzz.” Try for yourself and check the answer!
Here is the solution:
Wait…it’s not over though! The whole purpose of the algorithm is to customize the runtime correctly. Imagine if the range increases from 1-15 to 1-100. The compiler will check each number to determine whether it is divisible by 3 or 5. It would then run through the numbers again to check if the numbers are divisible by 3 and 5. The code would essentially have to run through each number in the array twice — it would have to runs the numbers by 3 first and then run it by 5. To speed up the process, we can simply tell our code to divide the numbers by 15 directly.
Here is the final code:
As Simple as that, you can use any language of your choice and get started Enjoy Coding
