Suppose that a recursive function with integer parameter n has a base case of 0, and for each non-base case, the function makes a recursive call with argument n+1. If the function is initially called with an actual argument of n = 3, the function call will
A) cause an infinite chain of recursive calls.
B) return after a chain of 2 recursive calls.
C) return after a chain of 3 recursive calls.
D) return after a chain of 4 recursive calls.
E) None of the above
What is wrong with the following recursive algorithm?Algorithm recursiveAlgorithm(n) if (n equals 0) return recursiveAlgorithm(1) end if return n + recursiveAlgorithm(n-1)end recursiveAlgorithm
A. The base case calls the recursive algorithm B. The base case should be 1 C. The general case does not reduce the size of the problem D. It should not have a base case
