Simple Programming Problem but How Many Ways to Do It?

[PHPBABY3]

Program 1 returns a Boolean value call it A.
Program 2 returns a Boolean value call it B.
We want one program that returns A ^ B (the value of A and B).
We don’t want to call 1 and 2.
We want to take the code in these two programs and create a new program.

Assume we have the common commands and expression elements e.g. those of PHP.
How many different programs can we create?

It's actually been a long time since I've seen a homework question on USENET.

Maybe one of those that promised to not use ChatGPT ;)

I've never seen one. This is part of what I (arguably) believe is the most important problem of Computer Science - both in theory and practice.
