11. Given the following recursive deﬁnition f(1) = f(2) = 2 f(n) = 2∗f(n−1)+ f(n−2) write the C++ code to implement the corresponding program and use it to calculate f(5). (You need to write both the main() and the f(n) function.) How many invocations are made to the function f when calculating f(5) ?

Consider the following recursive function: def rec1(aList,first,last): if first==last: return aList[first] else: return aList[last]*rec1(aList,first,last-1) Show the output of the following call (show your work and all recursive calls): print(rec1([1,2,3,4,5,6,7],3,5))? describe the task of the rec1 function.
C/C++ & MIPS The function ?add(?,?) for two positive integers 0≤?, and 0≤?, is defined as the following:?add(?,0)=?; ?add(?,?)=?add(?,?−1)Write a recursive version of ?add() in C or C++, then use this program to develop a MIPSprogram that gets as input two integers 0<? ≤255, and 0<? ≤255, and returns theresult of ?add(?,?) in $v1.Your deliverable should be the C/C++ code and the MIPS assembly function-code
Need some help with this c++ problem In order to compute a power of two, you can take the next-lower power and double it. For example, if you want to compute 211 and you know that 210 = 1024, then 211 = 2 × 1024 = 2048. Based on this observation, write a recursive function int pow2(int n) where n is the exponent. If the exponent is negative, return -1. int pow2(int n) { ..... }
please code in python Write a recursive function power(x, n), where n is 0 or a postive integer. For example, power(2, 10) will return 1024. Write a suitable base case, and for the general case use the idea that x**n = x * (x**n-1).
I need help in this practice problem of C (notC++ or C#) without using strings or arrays. Write a recursive function on the following formulas and problems a(n)=a(n-1)+1 where a(1)=1 b(x)=b(x-1)*b where b(1)=1 f(n, m)=f(n-1, m+1) +f(n-2, m+1)+m where f(1, m)=1 and f(0, m)=0
1.The following is the C code that you need to implement for this lab: uint8_ t f(uint8_tn) return(n<2)?(n):(f(n-1)+f(n-2)); The main function can be assumed as follows: int main() uint8_ t x; x=f(???); return 0; Obviously, " ? ? ? " is representing a value used to test the algorithm! Is "f"recursive? a.No answer text provided. b.Yes c.no d.depends on whether it is in for main 2.First, make the code in the previous question an actual C program so that it can be compiled and it runs. Play with it so that you feel comfortable with the logic of the code. Then implement the code in TTPASM. Note that you need to preserve the actual C code structure, this means you cannot it into a non-recursive subroutine. Furthermoreall conventions discussed in class regarding subroutines must be followed. The idea is that I should be able to substitute f with my own code, and main should work. Or, I can substitute main with my own, and f should work. Attach the source code of your assembly…
Consider the following recursive C function, assume that get (6) function is being called in the main (), then how many times will the get () function be invoked before returning to the main () function? Explain the execution logic. Assume that you have a main () function, inside the main () function, call get () and pass the argument 6, get (6). void get(int n) { if(n<1) return; get(n-1); get(n-3); printf("%d", n); } pls explain with flowchart.
c++ Implement a function that recursively calculates the nth number in the Fibonacci sequence of numbers. The Fibonacci sequence starts at 0 and 1. Each number thereafter is the sum of the two preceding numbers. This gives us the following first ten numbers: 0,1,1,3,5,8,13,21,34, .... Input Expected output0 01 17 139 34
Write a C++ function using recursion that returns the Greatest Common Divisor of two integers. The greatest common divisor (gcd) of two integers, which are not zero, is the largest positive inteteger that divides each of the integers. The code should follow the exact function declaration: int GCD(int number1, int number2);
How do I write the code for Fibonacci Function in C program? This is done in Macbook Terminal in Linux! I need to only print out by 5 each Fibonacci number (0, 5, 10, 15, 20, 25, 30, 35, 40, 45) and this code needs to be written using recursion. The Fib() function should return an unsigned long, which is the final calculation of the Fibonacci sequence sent to it. So, Fib(5) should return the value 5. Please include the output results
