In your toy example it looks retarded in every way, but I get what you mean and the answer is definitely 2. You want a return statement in the main function block to explicitly tell what the function does in the main/default scenario, then you want a return inside an if block to tell what it does in that specific edge case.
For example, the major thing about fibonacci is that it computes f(n-1) + f(n-2). You want to write this thing in the main function block because that's what this function is all about. Then, there is the edge case for f(0) and f(1) which should be relegated inside an if block.
unsigned long fibonacci(unsigned int n) {
if (n < 1) return 1;
return fibonacci(n-1) + fibonacci(n-2);
}

With an explicit return at the end of the function you are making the default behavior clear. So 1 is less explicit and 3 is even worse as it makes everything more ambiguous.

Lmao ))

Anyone who says 2 over 1 is a code monkey mathlet. It demonstrates software "engineer" design pattern thinking instead of logic.

1 is verbose reduntant pajeetware
this, except don't use tree recursion for fibonacci desu

Tell me how I know never took a single uni level math course above precalc.

>you should write retarded if statements because of muh math
lol
lmao
get outta here rajesh
