Consider the following two equivalent programs written in Python and C++ respectively. def $$f(A,B)$$ : $$B+=1$$ if $$A<=0:$$ return $$B$$ else: return $$f(A?1,B)$$ double $$f($$ int $$A$$, int $$B)\{$$ $$B+=1;$$ if (A<= $$?)\{$$ return $$B;$$ \} else \{ return $$f(A?1,B);$$ \} What is the time complexity of the function $$f()?$$ Select one: A. $$O\left(2^{?}\mathrm{A}\right)$$ B. $$O\left(A^{?}2\right)$$ C. $$O\left(A{\log }_{?}2\mathrm{A}\right)$$ D. None of the others E. $$O(A)$$
