Hello, I’m Yuki, a student engineer.
If you want to become an engineer, you probably see FizzBuzz problems in entry-level tests or intern coding tests.
I think FizzBuzz problems are a great way to learn programming thinking, so I’m going to write an article about them.
What is FizzBuzz proplem?
The FizzBuzz problem was proposed by Jeff Atwood, co-owner of Stack Overflow.
It is often used to identify whether an aspiring programmer can code.
The FizzBuzz problem is here.
Write programming to output numbers from 1 to 100.
However, when the number is a multiple of 3, output Fizz instead of the number, when the number is a multiple of 5, output Buzz instead of the number, and when the number is a multiple of 3 and 5, output FizzBuzz.
How to implement the code
The algorithm for the FizzBuzz questions is as follows.
Multiples of 3 and multiples of 5 → FizzBuzz
Multiple of 3 → Fizz
Multiples of 5 → Buzz
Other multiples→Output a number
Here is the implementation code
for i in range(1,101): if i % 3 == 0 and i % 5 == 0: print("FizzBuzz") elif i % 3 == 0: print("Fizz") elif i % 5 == 0: print("Buzz") else: print(i)
1 2 Fizz 4 Buzz Fizz 7 8 Fizz Buzz 11 Fizz 13 14 FizzBuzz
At the end
Many programmers seem to be solving FizzBuzz problems with restrictions such as how short the code should be, how it should be implemented without using the “%” sign, and so on.
If you can solve FizzBuzz problems, you are on your way to becoming a great programmer.
