- 2- Write a function sumsteps2 that calculates and returns the sum of 1 to n in steps of 2, where n is an argument passed to the function. For example, if 11 is passed, it will return 1 + 3 + 5 + 7+ 9 + 11. Do this using a for loop. Calling the function will look like this: >> sumsteps2 (11) ans = 362- The factorial n! of a positive integer n is defined as n! = 1*2*3 . .. * (n-1) * n Where 0! = 1 Write a function to calculate the factorial of a number. Argument: A number n of type unsigned int. Returns: The factorial n! of type long double. Write two versions of the function, where the factorial is • calculated using a loop calculated recursively Test both functions by outputting the factorials of the numbers 0 to 20.How many times does a for loop run? A. A for loop runs a random number of times. B. The value of the for loop variable defines the number of times a for loop may run. C. A for loop runs once. D. A for loop runs once for each item in the sequence included in the for statement. How do the lines of code in the body of a function get executed? A. As soon as the function is defined the code is executed B. The function must be called within the program C. The name of the function is passed in the exec command D. Based on the function's condition What happens when a function is called? A. The function is defined. B. The function is deleted. C. Program execution jumps to the function definition and executes the code in the function body. D. All of the above.
- Programming Assignment:Here is a loop that starts with an initial estimate of the square root of a, x, and improves it until itstops changing:while True: y = (x + a / x) / 2 if abs(y - x) < epsilon: break x = ywhere epsilon has a value like 0.0000001 that determines how close is close enough.Encapsulate this loop in a function called square_root that takes a as a parameter, chooses areasonable value of x, and returns an estimate of the square root of a.To test the square root algorithm in this chapter, you could compare it with math.sqrt. Write afunction named test_square_root that prints a table like this:1.0 1.0 1.0 0.02.0 1.41421356237 1.41421356237 2.22044604925e-163.0 1.73205080757 1.73205080757 0.04.0 2.0 2.0 0.05.0 2.2360679775 2.2360679775 0.06.0 2.44948974278 2.44948974278 0.07.0 2.64575131106 2.64575131106 0.08.0 2.82842712475 2.82842712475 4.4408920985e-169.0 3.0 3.0 0.0The first column is a number, a; the second column is the square root of a computed with the[your…Question 1 Not complete Marked out of 1.00 Flag question Write a recursive function named count_non_digits (word) which takes a string as a parameter and returns the number of non-digits in the parameter string. The function should return 0 if the parameter string contains only digits. Note: you may not use loops of any kind. You must use recursion to solve this problem. You can assume that the parameter string is not empty. For example: Test Result print(count_non_digits ('123')) print(count_non_digits ('2rPTy5')) print(count_non_digits ('hello world')) 11 Precheck Check 0 4 Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) 1Boolean Function - Pythona) Define a function, isInRange() with an integer parameter, x. This function returns true if the integer number x is in the range (-100, 100). Otherwise, return false.b) Define a main() function, in which a loop will be created to do the following ten times: - Get a random integer, n, in the range (-500, 500).- Call isInRange(x) function to determine and print out if the number n is in the range.c) Call main() function to initiate the tasks to be performed.
- Write and test the “digit” function: Function Prototype: int digit(int n,int k)This function returns the kth digit of the positive integer n. For example, if n is the integer 29,415 that is entered by user , then the call digit(n,0) would return the digit 2, and the call digit(n,2) would returnthe digit 4. do this only by using functions and loops. arrays are not allowed. example :Input: n = 29415 , k = 1 output: 9 Input: n = 2 , k = 1 output: index out of bound (return -1)Write code that uses any type of loop. The code should continually ask for a user input and sums all user inputs that are divisible by 2. The loop should continue until the user enters a negative number. The code should output the sum a single time once user entry has completed. You may assume all libraries and namespaces have been previously written into the code, you are just writing everything that would go inside the main function (beyond the return 0:).Write a recursive function named largestDigit that accepts an integer parameter and returns the largest digit value that appears in that integer. Your function should work for both positive and negative numbers. If a number contains only a single digit, that digit's value is by definition the largest. You must not use any loops; you also cannot use the string type or any library functions. Your function must be recursive. Complete the following file: largestDigit.cpp 2 // You may use this helper function 3 int max(int a, int b) { return a < b ? b : a; } 4 5 int largestDigit(int n) if((n<0) && (n/10 if(n<0) n = 0)) return n; 8 -n; static int maxi 9 n%10; 0) return maxi; maxi = max(maxi, n%10); return largestDigit(n/10); = 10 if((n/10) 11 12 13 14 15 16 } Submit Calling with Arguments Name Arguments Actual Expected pass largestDigit 135725 7 7 pass largestDigit 111211 2 2 fail largestDigit 100000 1 pass largestDigit 4530021 5 pass largestDigit 7639852 fail largestDigit 76352 6 pass…
