I also asked a little questions.

Quote:I want to make a function - pseudocode - that picks randomly between the numbers 0 to 7 and 20 to 23. How would you do it?

Here's an example pseudocode function that randomly picks a number between 0 to 7 and 20 to 23:

Code:

function random_number():
    // Generate a random integer between 0 and 1
    random_bit = random_integer(0, 1)
    
    // If the random bit is 0, pick a random integer between 0 and 7
    if random_bit == 0:
        return random_integer(0, 7)
    
    // If the random bit is 1, pick a random integer between 20 and 23
    else:
        return random_integer(20, 23)

...further explanations...


I'd like an uniform distribution and that what you suggest, although working, is not uniform.

I apologize for the confusion. You're right that the previous approach I suggested doesn't result in a uniform distribution, as it will pick numbers from the two ranges with equal probability but not uniformly within each range.

Here's a revised pseudocode function that should pick a random number uniformly from the given ranges:

Code:

function random_number():
    // Pick a random number from one of the two ranges with equal probability
    range_bit = random_integer(0, 1)
    
    // If the range_bit is 0, pick a random number between 0 and 7 inclusive
    if range_bit == 0:
        return random_integer(0, 7)
    
    // Otherwise, pick a random number between 20 and 23 inclusive
    else:
        return random_integer(20, 23)

Then it continues even if I say that the chat identified the problem but didn't solve it in the implementation. The interesting part is that the Issue is indeed recognized.

Identifying a problem (whatever it means) is not a great achievement.

It is important to take into account that ChatGTP is, in a nutshell, a probabilist model to chain words, which meaning is given by the reader.

It remember me of a monkey that has been taught with signs language: the monkey can learn sooner or later to master those signs meaning “give me a banana” or similar, but that’s it.
