Please assist me with these questions.(for the 1st part just complete the bolded area. All other areas have been completed. Then complete the 2nd part 1. Devise an algorithm to receive a positive number, n, and output all prime numbers that are smaller than n and have the digit 5. For example, if n is 100, the program should output 5, 53 and 59. Your solution should have a main algorithm and two sub-algorithms, let's call them prime(num) and has5(num). Trace your algorithm and sub-sub-algorithm for the input 15. You should provide pre- and post-conditions for all your 3 (sub)algorithms. Now, let's trace this algorithm for the input n = 15: For i = 2 to 14, we check if i is prime and if i contains the digit 5. The prime numbers less than 15 are 2, 3, 5, 7, 11, 13. Among these, only 5 contains the digit 5. So, the output for n = 15 is [5]. 2. I also need help with creating JavaScript code for the flowchart provided below. Note: You will have to implement several functions that…
Description Xiao Zhang is often distressed because there are too many things to arrange. Now he has n tasks at hand, and each task has a starting times, and an ending time e;. To complete a task, he must do it from the starting time to the ending time, and Xiao Zhang can only perform one task at the same time. Xiao Zhang wants to know how many tasks he can accomplish at most. Input The first line is an integer n (1sns300000), indicating the number of tasks Xiao Zhang has at hand. In the next n lines, each line contains two integers s₁, e¡ (1≤s;
[Python Language] A common back-of-the-envelope technique for estimating a runner’s marathon time is to take their best half-marathon time, multiply by two and add ten minutes. This works pretty well unless the marathon course is hilly.If it is hilly, we add an extra 20 minutes to the estimate. Write a program that takes two lines of input: a float giving the half- marathon time in minutes and an integer indicating whether the marathon course is hilly(1) or not (0). It prints a float giving the estimated number of minutes the runner will take to run the full marathon. Write your pro- gram in a file named marathon.py.
Please give me correct solution.
Could you make sure the code is correct. Please read the instructions carefully and the example runs. Thanks.
Practicing Loops. Einstein Private Elementary school has three classes in each of its 9 grades. 27 classes in total. It has kindergarten (grade 0) though 8th grade. The school allows parents to pay tuition over the nine-month school year. Tuition for kindergarten is $90 dollars every month. Tuition for the other grades is $50 times the grade level every month. (1st grade is $50 a month, second grade is $100 a month, etc.) Design a programming solution that outputs nine tuition payment bills for each of the 27 classrooms. Each bill must contain the grade number (0 through 8), the classroom number (1 through 3), the month (1 through 9) and the amount of the tuition due. Your output should look something like: Grade Classroom Month Tuition 0 1 1 90 0 1 2 90 0 1 3 90 0 1 4 90 ... 8 3 7 400 8 3…

5. Given an integer n, you need to find the digital root of that integer using a recursive function. If n has only 1 digit, then its digital root is n. Otherwise, the digital root is equal to the digital root of the sum of the digits of n. The process continues until a single-digit number is reached. For example, digital_root of 576 is calculated as: digital_root (576) = 5+7+ 6 = 18 digital_root (18) = 1 +8=9 digital_root (9) = 9 Programming Language :- C So, the digital root of 576 is 9
code in python (A) please Solve the so-called "Birthday Problem". Write a program that takes an integer ?N and uses the function np.random.randint (low = 0, high = N) from numpy to generate a random sequence of integers between 00 and ?−1N−1. Run experiments to validate the hypothesis that the number of integers generated until the first repeated value is approximately ?∗?2⎯⎯⎯⎯⎯⎯⎯√π∗N2. a) Write a function birthday(N) that returns the number of values generated until a value is repeated as a function of the range of possible values ?N (from 00 to ?−1N−1); b) Write a function birthday_sim(N) that repeats birthday(N) a total of n_sim = 20000 times and returns the average of all the numbers generated; c) Show on one plot that as ?N increases (with a doubling experiment), from ?=2N=2 to ?=1000N=1000, the value of birthday_sim(N) approaches ?∗?2⎯⎯⎯⎯⎯⎯⎯√π∗N2.

NOTE: Solve this as soon as possible, I need this urgently. (a). Write a function that takes an integer as input and finds whether it is a prime number or not . Function should return 1 if number is prime , 0 otherwise. In main(), ask the user to enter the number and call the funcltion. Based upon the value returned by the function , main() will display on screen, if the number is prime or not.
Write a recursive function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, the pattern generated is as follows: **** *** ** * * ** *** **** Also, write a program that prompts the user to enter the number of lines in the pattern and uses the recursive function to generate the pattern. For example, specifying 4 as the number of lines generates the preceding pattern.
