Base case doubt

#1

Which is better? Using n == 1 as a base case to prevent another call on the stack or using n == 0.

#2

It depends. Sometimes you need to return different values for both the base cases i.e. n== 0 and n == 1 . In that case , you don’t have a choice. Else, you can keep the base case as 0 but make sure the function never enters with a negative value else it may create unexpected results.
