to n. Calculate the complexity of your program.
Note: A sphenic number is a product of p*q*r where p, q, and r are three distinct
prime numbers. Example: 30 = 2 * 3* 5; 42 = 2*3*7; 66 = 2*3*11

- As the algorithm performs division of numbers with high precision, it is very common to see really big numbers after the period (for example: 1200.2300001), which is not desirable because of several reasons: may cause confusion to some users when they see such big numbers; uses more memory to store a bigger number; it just does not make sense to display currency number in this format. For this reason, you are going to implement a utility function to format any number into the appropriate currency format, using 2 decimal places. For example: The number 1200.2300001 would be became: 1200.23PYTHON A perpetuity pays a coupon value of C each and every period forever. Given a discount rate of r, the value of a perpetuity is given by V=∑t=1∞C(1+r)t Compute the value of a perpetuity using the summation formula. In the function below, use a for loop to estimate the value of a perpetuity, approximated to N periods. def summation_formula(C,r,N):Write a program function that will find and add two digits odd numbers and subtract four digits odd numbers which are in the range from 1 to first five digits of your student ID (make sure you use WHILE loop). Then find the Cyclomatic Complexity of the code segment. 16214
- Python only Rajesh loves lucky numbers. Everyone knows that lucky numbers are positive integers whose decimal representation contains only the lucky digits 4 and 7. For example, the numbers 47,744, 4 are lucky and 5, 17,467 are not. Let Fa(x) equal the number of digits d in the decimal representation of the positive integer x. Chef is only interested in F4(x) and F7(x) functions. For a given positive integer N, he wants to know the total number of distinct pairs (L; R) such that F4(L) + F4(L + 1) + ... + F4(R) equals F7(L) + F7(L + 1) + ... + F7(R) and 1In python, The function decodeFromAscii takes a list L of integers in the range 32 through 126. Each item in L is an ASCII code representing a single printable character. The function accumulates the string of characters represented by the list of ASCII codes and returns that string. For example, decodeFromAscii([78, 105, 99, 101, 33]) returns "Nice!" because N is chr(78), i is chr(105), c is chr(99), etc. Note: ASCII was created in the 1960's so programmers could have a standard encoding for common keyboard characters as numbers. It was later expanded to create Unicode so that characters from languages other than English, mathematical symbols, and many other symbols could also be represented by numerical codes. For example: Test Result print(decodeFromAscii([36, 49, 44, 48, 48, 48])) $1,000 print(decodeFromAscii([115, 110, 111, 119])) snowComputer Science please in java. must use while loop.python with a function “harmonic(n)” that computes the n-th harmonic number, write a function “harmonic_all(n)” that returns the number of values generated until all values are obtained as a function of the range of possible values n, then write a function “harmonic_sim(n)” that repeats “harmonic_all(n)” a total of n_sim = 100 times. function harmonic(n) is written: def harmonic(n) : harmonic = 1.00 for i in range(2, n + 1) : harmonic += 1 / i return round(harmonic,2) please help with harmonic_all and harmonic_simPython only Rajesh loves lucky numbers. Everyone knows that lucky numbers are positive integers whose decimal representation contains only the lucky digits 4 and 7. For example, the numbers 47,744, 4 are lucky and 5, 17,467 are not. Let Fa(x) equal the number of digits d in the decimal representation of the positive integer x. Chef is only interested in F4(x) and F7(x) functions.

Computes the smallest x that satisfies the chinese remainder theorem for a system of equations. The system of equations has the form: x % nums[0] = rems[0] x % nums[1] = rems[1] ... x % nums[k - 1] = rems[k - 1] Where k is the number of elements in nums and rems, k > 0. All numbers in nums needs to be pariwise coprime otherwise an exception is raised returns x: the smallest value for x that satisfies the system of equations.Use Python Write a function, print_integers_less_than(n), which takes an integer parameter n and prints each integer k which is at least 0 and is less than n, in ascending order. Hint: use a simple for loop. For example: Test Result print_integers_less_than(2) 0 1 print_integers_less_than(5) 0 1 2 3 4 print_integers_less_than(-3)Given the recursive function below where n is an integer: if n = 0 or n = 1 or n = 2 f(n) = {f(n – 2) + f(n – 4) otherwise Which of the following statements is true? IMPORTANT: There is no "Check" button for this question. You can change the answer as many times as you like. Select one: O a. The function terminates if and only if n is 1 or even. O b. The function terminates if and only if n24. O . The function terminates if and only if n=1 or n is even and greater or equal to 0. O d. The function terminates if and only if n is 0, 1 or 2. O e. The function terminates if and only if n20.Using python, please explain 1: A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.SEE MORE QUESTIONSRecommended textbooks for youDatabase System ConceptsComputer ScienceISBN:9780078022159Author:Abraham Silberschatz Professor, Henry F.
