# Exercise 1. Implement the algorithm covered in lectures that determines if an integer n is prime. Your function should return True, if n is prime, and False otherwise. Your algorithm has to be effective for n ~ 1,000,000,000,000.def isPrime(n):
Let A = {a, b, c} and B = {u, v}. Write a. A × B b. B × A

Which one is correct for the following snippet of code? def factorial1(x): if x== 0: return 1 return x *factorial1(x-1) def factorial2 (x,y=1): if x== 0: return y return factorial2 (x-1,x*y) Group of answer choices a) Both factorial1() and factorial2() aren’t tail recursive. b) Both factorial1() and factorial2() are tail recursive. c) factorial1() is tail recursive but factorial2() isn’t. d) factorial2() is tail recursive but factorial1() isn’t.
Implement the Function has_error Implement the function according to the specification. Use the test script testcurrency.py to aid your development before checking your answer below. CANNOT USE IF/CONDITIONAL STATEMENTS Instead, you should use what you know about boolean expressions def has_error(json):"""Returns True if the response to a currency query encountered an error. Given a JSON string provided by the web service, this function returns True if thequery failed and there is an error message. For example, if the json is '{"success":false,"src":"","dst":"","error":"Source currency code is invalid."}' then this function returns True (It does NOT return the error message'Source currency code is invalid'). On the other hand if the json is '{"success": true, "src": "2 United States Dollars", "dst": "1.772814 Euros", "error": ""}' then this function returns False. The web server does NOT specify the number of spaces after the colons. The JSON '{"success":true, "src":"2 United…

Complete the program shown in the 'Answer' box below by filling in the blank so that the program prints 2 2 We're dead, Fred There are multiple solutions; any one will do. Answer: def silly2(nums, indices, extra=None): print(len(nums), len(indices)) new_indices = [] for i in indices: if i >= 0 and i < len(nums): new_indices.append(i) if extra: new_indices.append (extra) try: for index in new_indices: if index < len(nums): print(nums [index]) except IndexError: print ("We're dead, Fred") silly2
