Examples: abcd becomes cdab. abcde becomes deCab AhmadAlami becomes AlamiAhmad Page 1 of 2 Your program must: • Implement function void reflect (char* str) which receives a string (array of characters) and mirrors it. This function does not print anything. • Read from the user (in main()) a string and then print the string after calling function reflect(). • Use pointers and pointer arithmetic only. The use of array notation and/or functions from the string.h library is not allowed.
- Domino cycledef domino_cycle(tiles):A single domino tile is represented as a two-tuple of its pip values, such as (2,5) or (6,6). This function should determine whether the given list of tiles forms a cycle so that each tile in the list ends with the exact same pip value that its successor tile starts with, the successor of the last tile being the first tile of the list since this is supposed to be a cycle instead of a chain. Return True if the given list of domino tiles form such a cycle, and False otherwise. tiles Expected result [(3, 5), (5, 2), (2, 3)] True [(4, 4)] True [] True [(2, 6)] False [(5, 2), (2, 3), (4, 5)] False [(4, 3), (3, 1)] FalseQuestion > Not complete Marked out of 1.50 Flag question Previous page Write a recursive function named get_palindromes (words) that takes a list of words as a parameter. The function should return a list of all the palindromes in the list. The function returns an empty list if there are no palindromes in the list or if the list is empty. For example, if the list is ["racecar", "hello", "noon", "goodbye"], the function should return ["racecar", "noon"]. A palindrome is a word that is spelled the same forwards and backwards. Note: The get_palindromes() function has to be recursive; you are not allowed to use loops to solve this problem. For example: Test words = ["racecar", "hello", "noon", "goodbye", "test", 'aibohphobia'] ['racecar', 'noon', 'aibohphobia'] print (get_palindromes (words)) print (get_palindromes ([])) print (get_palindromes (['this', 'is', 'test'])) Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) Result Precheck Check [] [] Next pagePYTHON CODING This function takes a list of points and then returns a new list of points, which starts with the first point that was given in the list, and then followed by points closest to the start point.

The input begins with an integer indicating the number of integers that follow./// in python /// def get_words_last_1():"""The function should take a list of wordsas an input parameter and return a new list of stringswith the last character removed.

When you are asked to "write a Python expression" to complete a task, you can either give the expression in one line or break down the task into several lines. The last expression you write must represent the required task. Question 1 (Reduce parentheses) Give an equivalent version of this expression by removing as many redundant parentheses as possible, without expanding the brackets or simplifying. (x**(2**y))+(y*((z+x)**3)) Question 2 (Translate arithmetic concept into Python) You are given a list of numbers, named numbers, containing 3 integers. Write a python expression (one line) that evaluates to True if and only if the product of any two numbers in the given list is greater than the sum of all three numbers. Note: the product of two numbers, x and y is x*y. Question 3 (List/table access) You are given a table,…The mapped list pattern Our second pattern is the mapped list pattern, described in video 4 3 mapped list pattern. Often we need to write a function that takes a list as a parameter and returns a new list in which each item in the original list is "mapped" to a new item in the result list. For example, the following function takes a list of numbers as a parameter and returns a list of all the numbers squared, e.g. squares ( [1, 3, 7]) returns [1, 9, 49]. def squares (nums): "Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result Although this is just a special case of the accumulator pattern, it is so common that we give it its own name: the mapped list pattern. Consider the following function: def squares(nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result If the main program calls print(squares ( [5, -3, 2, 7]) what is the state table for the function…
