8. Discuss whether the following task is possible to implement. The argument and the discussion are important.Infinite runs (2): An IDE company wants to improve its product by introducing more checks for the programmers. In particular, they want to detect infinite cycles at compile time. You should check statically whether it ispossible that you end up in an infınite cycle and issue a warning.

Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counter class is passed as a parameter, the count property of that instance should be incremented based on the number of recursive calls. The __str__ method should return the count property's value as a string. ----------------------------------------------------------------------------------- """ File: fib.py Project 11.7 Employs memoization to improve the efficiency of recursive Fibonacci.

Count divisibles in range def count_divisibles_in_range(start, end, n): Let us take a breather by tackling a problem simple enough that its solution needs only a couple of conditional statements and some arithmetic, but not even one loop or anything even more fancy. The difficulty is coming up with the conditions that cover all possible cases of this problem exactly right, including all of the potentially tricksy edge and corner cases, without being off-by-one. Given three integers start, end and n so that start <= end, count how many integers between start and end, inclusive, are divisible by n. Sure, you could solve this problem with the list comprehension one-linerreturn len([x for x in range(start, end+1) if x % n == 0]) but of course the automated tester is designed so that anybody trying to solve this problem in such a blunt fashion will only find themselves running out of both time and space! Your code should have no loops at all, but use only integer arithmetic and…
19- java. Which of the following is a drawback of using recursion? It may be less efficient than an iterative version. It may have fewer lines of code than an iterative version. It uses lesser memory stack than an iterative version. It runs faster than an iterative version.
READY CAREFULLY Java add COMMENT TO CODE, please TEST-CASE on how you would test your solution assumptions and hence your code. Example of cases to be tested for are like : What if the array input which is expected does not exist - that is , input is a null. How should your code handle such a situation ? Maybe output some message like "Null input case, so no output"? What if the length of the array is one ?....so on and so forth. In this assignment you are required programs which takes as input two sorted arrays and returns a new array containing the elements found in both the sorted arrays. It is alright if the input arrays have duplicates, but the returned array should be duplicate free! Below is how the arrays are represented ARRAY1[] = [1, 5, 6, 6, 9, 9, 9, 11, 11, 21] Here length of ARRAY1 is m. ARRAY2[] = [6, 6, 9, 11, 21, 21, 21] Here length of ARRAY2 is n. Array to be returned would be: ARRAY[] = [6, 9, 11, 21] ANSWER THE QUESTION BELOW. Implement the function…
