Please help me with these question. I am having trouble understanding what to do
For each question draw a flowchart (with pen and paper). And includes it postconditions and preconditions
Ex 14) Devise an
Ex 15) Devise an algorithm to input a positive integer, n, – and by using ‘*’ characters – output the figure below that has n rows, with 3 ‘*’ characters in the top row and 3*n characters in the last row. For instance, if input is 5, the figure on the left (and if the input is 12, the figure on the right) should be generated by the program.

- Answer the given question with a proper explanation and step-by-step solution. can you use pythonarrow_forwardPlease 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…arrow_forwardQuestion 1: Please develop a program. The program shows a O(n^2) time complexity. You may design nested loops. When you input a number, the output should be how many times of the loops. For example, if your input is 10, the number of loops should be 100 times, 200 times, 300 times, etc. The number of loops do not have to be an accurate number. Question 2: Please develop a program. The program shows a O(nlgn) time complexity. You may design nested loops. When you input a number, the output should be how many times of the loops. For example, if your input is 10, the number of loops should be 30 times, 60 times, etc. The number of loops do not have to be an accurate number.arrow_forward

Then proceed to write an algorithm that will check within the given string ‘s’, the most vowels found within any substring of ‘s’ of given length ‘i’. You may return an integer for the number of vowels found as the output, see examples below for further explanation • For example, if the user inputs the string; s = “iopuuugab” and an integer i = 3, then the output of “3” will be returned as the string “uuu” contains three vowels • Second example: if the user inputs string “gaspesie” and i =“3” then the output returned is “2”, the strings “esi” and “sie” both contain 2 vowels (note: the vowels do not need to be consecutive) • Third example: if the user inputs the string “Lynx” and integer = “4”, output would be “0” as there are no vowels present. • Fourth example: if the user inputs the string “hello” and integer “2”, output would be “1” as the combinations yield only one…arrow_forward
