FIZZBUZZ

[RWAP]

I was just reading that 99/100 job applicants for programming jobs apparently cannot write a short "fizzbuzz" program when given 10 minutes to do so in an interview.

I was wondering what the best solution (shortest, least memory or most elegant are all acceptable) would be on a ZX81

The rules are simple -
write out the values 1 to 100 on screen
If the value is divisble by 3 write 'FIZZ' after the number
If the value is divisble by 5 write 'BUZZ' after the number
If the value is divisble by 3 and 5 write 'FIZZBUZZ' after the number

Hi!

I think it´s a good drinking game as well

Another one. Pure BASIC, more complex, but much faster!

Another one, this time in pure forth
Load the program and type FIZZBUZZ to run it.

Code: Select all

: FIZZBUZZ
   101 1
   DO
     CR I DUP DUP .
     3 MOD 0=
     IF ." FIZZ" THEN
     5 MOD 0=
     IF ." BUZZ " THEN
   LOOP
;

hi kmurta!

can you tell me something about this forth-version? it´s spanish?

This small forth was published in the brazilian magazine "Micro Sistemas" and can be downloaded from http://zx81.eu5.org/files/soft/ms/Forth.zip.

It was also incorporated in the emulator VB81 Xur. See more information here http://forth-retro.pagesperso-orange.fr/index-en.htm.

Hi

Wow, we have a complete rainbow of solutions here !!!

A very good Sinclair Basic version by Siggi
A very good Speed Optimized version by Math
and a very good Forth Version By Kmurta

This is my asm version. I need almost 10 minutes to write and debug it, reusing an routine to write numbers in decimal form



BTW: I think that the Scroll is not necessary, may be you can think the result is not so nice, but I think that the Rules say print on the screen and my version does just it
In one way this is my Think Out of The Box solution dedicated to the Mensa members (Sir Clive included)

Hi Gus,

You are correct in that there is no rule about having one line per unit, but then surely points are awarded for artistic merit also as programmers need to not only understand the parameters of their remit, but what works well in the hands of a client.

However, your machine code program does break one rule - ie. if a number is divisible by 3 AND 5, then it should display FIZZBUZZ, not FIZZ BUZZ

Hi Rich,

mmm in the artistic side of my solution you are missing some fact: I don't say it before, but if you look at the screen very carefully, in the same way that you must look the Magic Eye 3D books you will see some secret part of the Ferranti ULA's

However, your machine code program does break one rule - ie. if a number is divisible by 3 AND 5, then it should display FIZZBUZZ, not FIZZ BUZZ

I must admit that you are right here, and now my insolent asm version completes the rainbow...
