In lisp programming Consider the two versions of the function computing the combinations. Add a global variable counter and increment it by one at the top of both functions. This will count the number of function calls required to complete the calculations in each case. Try the two versions of the function for a few pairs of numbers n and m and print out the value of the counter after each of them. Don't forget to reset the counter to 0 before each call. Comment on the observed difference between the numbers of function calls

Write a function that does the following for the given values: add, subtract, divide and multiply. These are simply referred to as the basic arithmetic operations. The variables have to be defined, but in this challenge they will be defined for you. All you have to do is check the variables, do some string to integer conversions, use some if conditions, and apply the arithmetic operation. Examples operation ("1", "2", operation ("4", "5", operation ("6", "3", "add" ) → 3 "subtract") → -1 "divide") → 2

Pressure in U.S. customary units is measured in psi (pound per square inch). In SI metric units pressure is measured in Pa (N/m2). Write a user-defined MATLAB function that converts pressure given in units of psi to pressure in units of Pa. For the function name and arguments, use [Pa] = Psi- ToPa (psi). The input argument psi is the pressure in units of psi to be converted, and the output argument Pa is the converted pressure in units of Pa (rounded to the nearest integer). Use the function in the Command Win- dow to: (a) Convert 120 psi to units of Pa. (b) Convert 3,000 psi to units of Pa.

Write a function that implements the quadratic equation. Given three inputs (a, b, and c), calculate the roots (r1 (+) and r2 (-)) of the quadratic formula. Review 19 Write a function that implements the quadratic equation. Given three inputs (a, b, and c), calculate the roots (r1 and r2) of the quadratic formula. Call your function Roots a = 1 b = 2 c = -3 [r1,r2]=Roots(a,b,c)

Write a function count_evens() that has four integer parameters, and returns the count of parameters where the value is an even number (i.e. evenly divisible by 2). Ex: If the four parameters are: 1 22 11 40 then the returned count will be: 2 Hint: Use the modulo operator % to determine if each number is even or odd. Your program must define the function:count_evens(num1, num2, num3, num4) python # Define your function here if __name__ == '__main__': num1 = int(input()) num2 = int(input()) num3 = int(input()) num4 = int(input()) result = count_evens(num1, num2, num3, num4) print('Total evens:', result)

I do not know how to do this problem from my Computer Science ZyBooks Chapter 6 assignment. I have attatched an image of the problem, and I need to write the code in Python. I am not sure how to define the functions correctly or how to take a list as a parameter and return a boolean, so any help would be greatly appreciated! Thank you!

First write a function f to generate and return a random number between 0 to 100 In the main function, you keep calling function f until the returned value is less than 10 Then you should print out how many times the function f has been called. Note that every time f will only return a single random number, and the declaration of f is as follows: int f() For instance, if f returns 23, 89, 10, 1, then your program should print 4 on the screen. C++ language Hint 1. You can implement the function using different methods, like the static variable Hint 2. You can use the modular operator to shrink the generated random value, i.e., random() % 101 will guarantee the result is between 0 and 100.

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 =わ 2 ×ばつかける 1024 =わ 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) { ..... }

This is for python, how would i go about doing this?

Write a function to check three given integers and return their sum. However, If one of the values is the same as another of the values, then both the values are not counted in the sum. In Ruby language.

In the U.S. fuel efficiency of cars is specified in miles per gallon (mpg). In Europe it is often expressed in liters per 100 km. Write a MATLAB user- defined function that converts fuel efficiency from mpg to liters per 100 km. For the function name and arguments, use Lkm=mpgToLpkm (mpg). The input argument mpg is the efficiency in mi/gl, and the output argument Lkm is the efficiency in liters per 100 km (rounded to the nearest hundredth). Use the function in the Command Window to: (a) Determine the fuel efficiency in liters per 100 km of a car whose fuel effi- ciency is 21 mi/gal. (b) Determine the fuel efficiency in liters per 100 km of a car whose fuel effi- ciency is 36 mi/gal.

Write a function that receives a positive integer n as a parameter, then it must calculate the sum 1+2+3+...+n. Finally return the result of the sum and in the main function print that result to the screen. The output of the program should be just the value of the sum. Look at the example. Input: A positive integer n Output: The result of the addition 1+2+3...+n Program execution example: Entry 6 Departure twenty-one Entry 5Output fifteen Entry 7 Departure 28

Write a function in Python language to take two integer parameters and return whichever value is nearest to the value 10, or return 0 if two integers are equal.
