Write a C++ program to compute the nCr
In permutations and combinations, the term nCr refers to n combinations taken r at a time.
n!
nCr =
r! (n – r)!
.Write a recursive function to find the factorial of a number.
.Use the defined function to compute the term nCr for the following scenario:
•The values of "n" and "r" are stored in two parallel arrays of any user defined size.
• You have to Read the arrays n and r at run time. Compute nCr for each corresponding terms in the array "n" and "r",
store it in another separate array and display the output array properly formatted.
• Also your program should print the current date and time using library functions.

(Program) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters, such as zerocount, onecount, twocount, and so forth, to 0. Then generate a large number of pseudorandom integers between 0 and 9. Each time 0 occurs, increment zerocount; when 1 occurs, increment onecount; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of time they occurred.
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).
please code in python Write a recursive function to add a positive integer b to another number a, add(a, b), where only the unit 1 can be added, For example add(5, 9) will return 14. The pseudocode is: # Base case: if b is 1, you can just return a + 1 # General case: otherwise, return the sum of 1 and what is returned by adding a and b - 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
Write a C program that checks whether the N real numbers entered by the user on the keyboard are in order from small to large. In your program, you need to write a function that checks whether a given double array is in order from small to large, returns 1 for ordered arrays, 0 for unordered arrays. The function must be recursive and no loops should be used within the function.
Write a recursive C++ program to find the GCD of two numbers and using this write a function to find the L.C.M of two numbers in O(1) time. GCD function should contain one line of code. Please answer only if you can fulfill the conditions else I will downvote.
In C++ Write a recursive function called PrintNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline. Ex. If the input is: 123 the output is: 12 9 6 3 0 3 6 9 12 #include <iostream> using namespace std; // TODO: Write recursive PrintNumPattern() function int main(int argc, char* argv[]) { int num1; int num2; cin >> num1; cin >> num2; PrintNumPattern(num1, num2); return 0;}
Write a function sum_of_digits(a,b), that takes two arguments a and b, computes a to the power of b, then recursively finds the sum of digits until there is only one digit left. You must PRINT all steps of the process as shown in the below example. sum_of_digits(5,3) will PRINT on the screen the following: 5ˆ3 = 125 = 1 + 2 + 5 = 8 sum_of_digits(2,8) will PRINT on the screen the following: 2ˆ8 = 256 = 2 + 5 + 6 = 13 = 1 + 3 = 4

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…
