- Given two integers x snf y, the following recurrsive definition determined the greatest common divisor of x and y, Write gcd(xy). Write a recursive function, gcd, that takes two integers as parameters and returns the greatest commmon divisorof numbers.Also write a program to test your function. Write a recursive function,reverseDigits, that takes an integer as a parameter snd returns the number with the digits reversed. Also write a program to test your application.Consider the following recursive function. What does it calculate in terms of x, y, and z? 01: Private Function CalcRecurse(ByVal x As Integer, ByVal y As Integer, ByVal z As Integer) As Integer 02: If x <= 1 Then 'Assume that CalcRecurse always starts with x > 1 03: Return y 04: Else 05: Return z + CalcRecurse(x - 1, y, z) 06: End If 07: End Function1.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…
- Write a recursive function called Mod which takes two positive integers argument (aand b) and returns a % b – the remainder of a dividing by b. You may not use a remainderoperator or built-in function.Write a recursive void function that has one parameter that is a positive integer. When called, the function writes its argument to the screen backward. That is,, if the argument is 1234, it outputs the following to the screen: 4321. I've literally tried to create this program and I have no idea how to make it work. Please help me. Is it possible to explain line by line what the code does?(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.
- 1. Bibi is challenging you to implement a recursive function to check integer X is a prime number or not. A prime number can be divided only by 1 and itself. You have to implement a recursive function “int isPrime(int x)” in C. Format Input The first line of the input contains an integer T, the number of test case. The next T line consist a positive integer X. Format Output For each test case, print Case #X: Y. X is the number of test case and Y is the result from function “isPrime(x)”. Constraints 1 <= X <= 100 2 <= X <= 1.000in C++ Complete function PrintPopcornTime(), with int parameter bagOunces, and void return type. If bagOunces is less than 2, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bagOunces followed by " seconds". End with a newline. Example output for ounces = 7:42 secondsWrite a recursive function called Mod (java) which takes two positive integers argument (a and b) and returns a % b –the remainder of a dividing by b. You may not use a remainder operator or built-in function.
- Write a recursive function called digit_count() that takes a positive integer as a parameter and returns the number of digits in the integer. Hint: The number of digits increases by 1 whenever the input number is divided by 10. Ex: If the input is: 345 the function digit_count() returns and the program outputs: 3 # TODO: Write recursive digit_count() function here. if __name__ == '__main__': num = int(input()) digit = digit_count(num) print(digit)In C++ Consider the following recursive function (Chapter 17, #9, modified) void recFun(int x) { if (x > 10) { recFun(x / 10); cout<< x % 10; } else cout<< x; } How can the code be modified so that the sum of all digits is printed?Write a statement that calls the recursive function BackwardsAlphabet() with parameter startingLetter. #include <iostream>using namespace std; void BackwardsAlphabet(char currLetter){if (currLetter == 'a') {cout << currLetter << endl;}else{cout << currLetter << " ";BackwardsAlphabet(currLetter - 1);}} int main() {char startingLetter; startingLetter = 'z'; /* Your solution goes here */ return 0;} Please help me with this problem using c++.
