Consider the following recursive definition of a factorial function.
int factorial ( int n)
{
if ( n == 0 || n ==1 )
return 1;
else
return n * factorial (n-1);
}
Suppose the function factorial (4) is invoke. Trace through the function call, explicitly show how the factorial function is repeatedly called and what is the value of n in each call. Also show the value returned by each call.
Give an iterative implementation of the factorial function.
factorial (4)
= 4 * factorial(3)
= 4 * 3 * factorial(2)
= 4 * 3 * 2 * factorial(1)
= 4 * 3 * 2 * 1
= 24
====================================
Iterative version:
int factorial ( int n)
{
int result = 1;
for(int i = 1;i<=n;i++){
result = result * i;
}
return result;
}

2. Consider the function george (int n) computed by the following recursive C++ code. int george (int n) assert (n >= 0) if (n < 2) return 1; else return 2*george ((n+1)/2)+2*george (n/2)+2 george((n-1)/2)+2*george (n/2-1); (c) Design a memoization algorithm to compute george(n) for any given n. You do not have to write C++ code. This algorithm should be much faster than the dynamic programming algorithm. What is its time complexity? 2. Consider the function george (int n) computed by...

C++ Assignment 4 - For example 2, write a non recursive version of this function... using a regular loop. Let's consider writing a function to find the factorial of an integer, N!. For example 7! equals 7*6*5*4*3*2*1. int myFactorial( int integer) if( integer == 1) return 1; else return (integer * (myFactorial (integer-1))); // action performed on call - pass into function "integer - 1" // action performed on return *
Q5. [5 marks] Consider the following recursive function: int Test (int number) //Line 1 //Line 2 if (number == 0) //Line 3 return number; //Line 4 else //Line 5 return (number + Test (number - 1)); //Line 6 //Line 7 a. Identify the base case. b. Identify the general case. c. If Test (0) is a valid call, what is its value? If not, explain why. d. If Test (5) is a valid call, what is its value? If not,...

The language has to be in C program 1. (a) rite a function, int factorial (int n), which returns n (the factorial of n, i e. 1 x2 x3 x...xn.) (b) Using int factorial (int n) above, write a program to compute 2. We want to find one of the roots of a cubic equation given by which is between 0 and 1 by an iterative method. Modify the equation above to 1 x Start with an appropriate initial value...
Recursive Tracing. For each call to the following method, indicate what value is returned: public static int mystery(int n) { if (n < 0) { return -mystery(-n); } else if (n == 0) { return 0; } else { return mystery(n / 10) * 10 + 9 - (n % 10); } Call Value Returned mystery(0) mystery(5) mystery(13) mystery(297) mystery(-3456) } Can any one help me with it?
Write a C program, containing the following functions. Function int recursive_fibonacci(int n) computes and returns the nth F(n) using recursive algorithm (i.e., recursive function call). Fibonacci numbers are defined by F(1)=F(2)=1, F(i) = F(i-1)+F(i-2), i=2,… . Function int iterative_fibonacci(int n) computes and returns the nth Fibonacci number F(n) using iterative algorithm (i.e., loop). The main function measures the memory usage and run time of iterative_fibonacci(40) and recursive_fibonacci(40), and does the comparison. To capture the execution time by millisecond, it needs...
