Fizz Buzz is a simple programming task often used in coding interviews. The task is to print the numbers from 1 to 100, but for multiples of 3 print "Fizz" instead of the number, and for multiples of 5 print "Buzz". For numbers which are multiples of both 3 and 5 print "FizzBuzz".
Implementing Fizz Buzz in TECO would be quite a challenge due to the language's design and constraints. TECO is not really meant for such tasks, as it is a text editor and correction programming language. However, I'll provide a rough example of how you might implement FizzBuzz in TECO, although it's somewhat complex and involves a few workarounds:
0uz ! Store 0 in register Z (counter) !
<qz+1uz ! Increment Z !
qz:< ! Inner loop, executes while Z is less than or equal to 100 !
qz\3%<iFizz$> ! If Z is divisible by 3, insert "Fizz" !
qz\5%<iBuzz$> ! If Z is divisible by 5, insert "Buzz" !
qz\3%qz\5%"nqz\*A$' ! If Z is not divisible by 3 or 5, insert Z (as a character) !
ia ! Insert a newline !
>' ! End of inner loop !
> ! End of outer loop !
This is a very rough, and not perfect, implementation. It doesn't properly handle numbers over 9, because TECO doesn't really support integer arithmetic in the way modern languages do. When we print a number, we're actually printing a character with the corresponding ASCII code, so numbers over 9 would turn into non-digit characters. Implementing FizzBuzz properly would likely involve manually converting numbers to digit strings, which would make the program quite a bit more complex.
In practice, you would rarely if ever use TECO for this sort of task. TECO was designed for editing text, not for general-purpose programming, and it lacks many of the features that make modern languages suitable for tasks like FizzBuzz. But, this does demonstrate some of the ways you can use TECO's unique features to solve problems.
