Write and test a function called pow_of_two() that takes a positive integer num as the input parameter and returns another integer that is the largest power of 2 and is less than or equal to num. For example, 1, 2, 4, 8, 16, 32.. are numbers that are the powers of 2, but 3, 5, 6, 7, 9, 10.. are not. Some sample outputs are here to test. pow_of_two(1) → 1 pow_of_two (2) -2 pow_of_two (12) pow_of_two (20) 8 16 pow_of_two (63) ➜32 pow_of_two (284) 256

Write a function that keeps computing the sum of the digits of x^n, until there is only one digit left. For example, sumOfDigits(2,5) returns 5, because 2 ^ 5 = 32 = 3 + 2 = 5 Another example, sumOfDigits(2,8) returns 4, because 2 ^ 8 = 128 = 1 + 2 + 8 = 13 = 1 + 3 = 4
In coral need please Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. Ex: If the input is 6, the output is 011. Your program should define and call a function: Function IntegerToBinary(integer num) returns nothing The function should output 1's and 0's representing the integer in binary (in reverse).
Write a program that does temperature converter :\n", "- The user will enter if he wants the result in Celsius or in Fahrenheit. Use the input function to read this option. \n", "- Ask the user the value of the temperature he wants to convert. Use the input function to read this value and convert accordingly.\n", "- If the user wants the temperature in Fahrenheit compute: $ Fahrenheit = Celsius*5/9+32$.\n", "- If the user wants the Celsius compute as follows: $ C = (F-32)*5/9 $.\n"
Define a function called digits that accepts two integer numbers m and n , and that displays m rows of n columns using the following pattern of digits. The first row starts with 1, the second row with 2, and so on until the 10th row starts with 0. Then the counter returns to 1 for the 11th row, then to 2 for the 12th, etc. For columns, the numbers are always incremented by 1 from the previous column, Except for the 9 that goes to 0. For example, the call digits(4, 7) must produce: 1234567234567834567894567890and the call numbers(12, 23) must produce: 123456789012345678901232345678901234567890123434567890123456789012345456789012345678901234565678901234567890123456767890123456789012345678789012345678901234567898901234567890123456789090123456789012345678901012345678901234567890121234567890123456789012323456789012345678901234Note that your function should not return anything, only display at the console.
Define a function which takes one parameter N, and use loop(s) to control and output a pyramid pattern as follows: print a total of N rows, the number of asterisks in each row equals the row number (e.g. the 1st row has 1 asteroid, the Nth row has N asteroids). Note the pattern should be center aligned. E.g. when N is 5, you will print the following pattern * * * * * * * * * * * * * * *
Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is: 3 8 Output: 8 3 Your program must define and call the following function. swap_values() returns the two values in swapped order.def swap_values(user_val1, user_val2) My Code: def swap_values(user_val1, user_val2):temp = user_val1user_val1 = user_val2user_val2 = tempreturn user_val1, user_val2 if __name__ == '__main__': user_val1 = int(input())user_val2 = int(input()) print(swap_values(user_val1, user_val2)) However the output is (8, 3) which is giving me incorrect due to formating, the output needs to be 8 3 without parantheses and comma.
Write a function that takes a list of marks from 10 courses as a parameter and calculates the CGPA of the marks for the best 7 courses according to the given conditions and returns the CGPA and the list of best 7 courses in a tuple. Then print the CGPA according to the output sample. Calculate the CGPA of the student based on the given conditions: If marks 80 - 100, grade point = 4.0 If marks 50 - 79, grade point = 3.0 If marks 0 - 49, grade point = 0.0 You need to calculate the CGPA in this way: CGPA = (sum of grades of 7 courses * 3) / 21 ================================================ Function Call 1: function_name([95,62,78,86,70,88,79,75,68,99]) Sample Output 1: Best seven marks: 95, 78, 86, 88, 79, 75, 99 Your CGPA is 3.57 Explanation 1: Here the best 7 marks are 95, 78, 86, 88, 79, 75, 99. The grades for these marks are 4.0, 3.0, 4.0, 4.0, 3.0, 3.0, 4.0 respectively. So based on the conditions the CGPA would be (((4.0+3.0+4.0+4.0+3.0+3.0+4.0) x 3) /21) = 3.57.…
i need to write a program that asks the user to input a number for the following forumla: e^x = 1 + x + (x^2/2!) + (x^3/3!) + (x^4/4!) + ... it should contain a function that accepts this number as an input argument and returns the exponential of this number using the formula and I also have to write a unit test to see if the program calculates the correct exponential result up to 2 decimal places by comparing it with the output of exp()
Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is: 3 8 the output is: 8 3 Your program must define and call the following function. swap_values() returns the two values in swapped order.def swap_values(user_val1, user_val2) I get all tests passed except one.: the one in the bold. It puts parentheses around the answer instead of what they want for output. 0 / 2 Output differs. See highlights below.

(Please make sure to match the screenshot below in output) Rolling a single six-sided die produces a random number between 1 and 6 with a uniform distribution. Rolling two dice produces a number between 2 and 12 with a binomial distribution. In this lab you will simulate a number of dice rolls and graph the number of occurrences of each value. 1) Create a function called rollDie() that takes no parameters, and returns a random value between 1 and 6. Do not seed the random number generator in this function. int rollDie() 2) Create a function called initArray() that takes a data array and the size of the array as parameters and fills each element with the summed results of rolling two dice. Do not assume that the data array has been initialized. void initArray(int data[], int size) 3) Create a function called sortArray() that takes an array and the size of the array as parameters, and sorts the array using the sediment sort. void sortArray(int data[], int size) The sediment sort works…

Write a program which will take marks of three quizzes as input, then call a function void ScaleUp(float q1, float q2, float q3) to check if the marks of any of the quiz ‘q’ is less than the average of rest of two quizzes ‘a’. If marks of any quiz is less than the average of the rest of two marks then add the difference between the average of the two quizzes and the quiz itself to q i.e., q = a - q, to scale up the quiz marks.For example, if q1 = 5, q2 = 8 and q3 = 9 then your function will change the marks of quiz 1 using the steps below:A = (q3 + q2 )/2 => (8+9)/2=> 8.5 Diff = A - q1 => 8.5 - 5 => 3.5 Q1 = Q1 + Diff => 5 + 3.5 => 8.5Note that the marks are input from the user, so there might be three cases I. if q1 < q2 + q3 orIi. if q2 < q1 + q3 orIii. if q3 < q1 + q2
