FizzBuzzer Advanced

Collapse Content Show Content

In the last challenge, you printed 100 lines and changed the numbers every 3 or 5 times. In this challenge, you will be given three integers n, a and b as input which will tell you how many lines to print and when to print Fizz or Buzz.

Write a program that prints the numbers from 1 through n. But for multiples of a print “Fizz” instead of the number and for the multiples of b print “Buzz”. For numbers which are multiples of both a and b print “FizzBuzz”.

Note: Print each item space-separated, and each test case on its own line.

Input Format
Boilerplate code is provided that passes in each input case into 3 variables: n, a and b.

If you want to process the input yourself, it uses the following format:

The input starts with T, the number of cases.
T lines follow, which each contains 3 integers in order for n, a and b.

Challenge

Print the numbers from 1..n (space-separated) except for every a and b times, when you should print "Fizz" and "Buzz".

I'm not sure what to do with the "Other Input" part. Can get everything else to work but don't know what is expected for "Other Input".

@Kirsten, it now shows all 4 cases.

Great, thanks!! That was a super quick fix : )

I think there could be a problem with this exercise. It was working fine on the previous page with the hard-coded numbers, but since changing these to the variables n, a and b for this advanced

cont...
exercise, it says the output is incorrect for all 4 cases. However, I tested my code in another compiler (using the same input cases) and the output was fine.

@Victoria, in this challenge you need to print each word space-separated and only add new lines after each test case. See the "Correct Output" shown above.

Thanks, that worked. :)

What I did is, make a string and assign values to it inside if statements in a for loop and if a certain condition was met than the string was changed to Fizz or Buzz and printed out, else I printed the number i which is <= n

Hope it helps. :P

How shoud I define a,b and n?

@saeed, I added a note about the input format.

    Scanner in = new Scanner(System.in);

    int loops = in.nextInt();

    for (int i = 0; i < loops; i++) {

        int max = in.nextInt();

cont...

        int fizz = in.nextInt();
        int buzz = in.nextInt();

        System.out.println(fizzbuzz(max, fizz, buzz));
    }

my code
Hey, guys. I got through the last challenge no problem. I also know how to use the Scanner for input, but it doesn't seem to want to run my code based on

cont...
the inputs that I'm taking. The syntax for the loops should be the same, so I'm not sure where I'm getting hung up. I am using print() so that everything prints on the same line, until the end where I use println() to end the test case.

You can use the provided boilerplate code to take in input, you don't need your own scanner. Note that each case consists of 3 numbers, n, a and b. Print out n items for each case.

no featured answer? I know my code sucks, so I'd like to see how it could be done better.

Confused about declaring n, a, and b. Normally in these challenges these are already declared, but I don't see it in this code. Here is the code I'm using which is which throws a compilation error, even though the same code worked on the previous challenge when n = 100, a = 3, and b = 5:

You can't just compare to n without having declared and assigned it. You need to declare the variables yourself (or use actual numbers.)

I'm expecting t to be an int....
"The input starts with T, the number of cases."

but it compile errors because it says T is a string!

Since this challenge involves standard input, you may want to use the boilerplate code to process the input for you.
