Part 1: Sin Tax Syntax [NEW PROBLEM] Complete the function sin_tax, which computes and returns the total cost to purchase several items, some of which might be subject to sin taxes. The function takes three arguments: items: a list of items to purchase (strings). If an item appears more than once, this means we want to buy it more than once. prices: a dictionary that maps an item (string) to its price (float) • tax rates: a dictionary that maps an item (string) to its sin tax rate (float). The rate is given as a decimal (e.g., 0.08 to represent 8%). ● If an item from items does not appear in tax rates, then that item is not subject to a sin tax. Assume that every string in items is a valid key in prices. Example #1: items: ['beer', 'wine', 'cigarettes'] prices {'beer': 18.95, 'cigarettes': 12, "wine': 20.0} tax rates: {'beer': 0.03, 'cigarettes': 0.1, 'wine': 0.05) 53.72 Returned: Example #2: items: ['wine', 'beer', 'wine', 'cigarettes', 'wine'] prices: {'beer': 15.5, 'cigarettes': 13, soda': 8.0, 'wine': 25.0} tax rates: {'beer': 0.035, 'cigarettes': 0.12, 'wine' : 0.07} Returned: 110.85

Data structures return_growing_num_list(max:int) -> list This function will be given a single number, it should return a list of strings of numbers. Each string in the list will only contain a single number repeated an arbitrary amount of times. The number each string will contain will be equal to the current string's index+1. The number in the string should be repeated the same number of times as the string's index+1. Each number in the string should be separated by a space. This list should stop when its size equals the max number specified. Example: max = 3 output = ['1', '2 2', '3 3 3'] max = 4 output = ['1', '2 2', '3 3 3', '4 4 4 4']
Complete the zero_extend_number() function that takes two parameters: • The integer parameter number which represents the number that needs to be zero-extended • The integer parameter length which represents the length of the number string that the function needs to return. The function returns a string representation of the parameter number with the length specified by the parameter length. If the number of digits in number is less than the length, then the function will need to zero-extend number by appending the required number of zeroes to the front of it. You can assume that the parameter length will always be greater than or equal to the number of digits in number. Some examples of the function being used are shown below: For example: Test Result print(zero_extend_number (1, 5)) 00001 print(zero_extend_number(10, 4)) 0010 Answer: (penalty regime: 0 %) Reset answer 1 v|def zero_extend_number(number, length):
Arrays write a C++ program that will declare two static arrays where each will hold the contents of a file (random.txt) of 200 integer values. Sorting Using the two arrays, call a private member function that uses the bubble sort algorithm to sort one of the arrays in ascending order. The function should count the number of exchanges it makes. Display this value. The program should then call a private member function that uses the selection sort algorithm to sort the other array. It should also count the number of exchanges it makes. Display this value. Searching Next, call a private member function that uses the linear search program to locate the value 869. The function should keep a count of the number of comparisons it makes until it finds the value. Display this value The program then should call a private member function that uses the binary search algorithm to locate the same value. It should also keep count of the numbers of comparisons it makes. Display this…

Q# Describe what a data structure is for a char**? (e.g. char** argv) Group of answer choices A. It is a pointer to a single c-string. B. It is an array of c-strings C. It is the syntax for dereferencing a c-string and returning the value.
palindromes Write a function palindromes that accepts a sentence as an argument. The function then returns a list of all words in the sentence that are palindromes, that is they are the same forwards and backwards. Guidelines: • punctuation characters .,;!? should be ignored • the palindrome check should not depend on case Sample usage: >>> palindromes ("Hey Anna, would you prefer to ride in a kayak or a racecar?") ['Anna', 'a', 'kayak', 'a', 'racecar'] >>> palindromes ("Able was I ere I saw Elba.") ['I', 'ere', 'I'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are Wow!") ['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] >>> palindromes ("Otto, go see Tacocat at the Civic Center, their guitar solos are wow!")==['Otto', 'Tacocat', 'Civic', 'solos', 'wow'] True
