Morse Code (python ) Morse code maps each letter of the alphabet to a series of dashes and dots (a = .-). The list of the Morse code for all English letters (from a to z) is provided below: [".-","-...","-.-.","-..",".","..-.","--.","....","..",".---","-.-",".-..","- -","-.","---",".--.","--.-",".-.","...","-","..-","...-",".--","-..-","-.-- ","--.."] Your goal here is to implement a function that takes a list of strings as its only parameter (called “words”). Each of the words can be transformed to Morse code by concatenation of a number of the above strings (without spaces). For example, the transformation of “ab” will be “.--...” (“.-” + “-...”). The word “ems” will also have the same transformation “.--...” (“.” + “--” + “...”). In this function, the goal is to return the number of the unique transformations in “words” list. Here is an example (none of this is needed to be printed, the function will only return one integer): Words = [“ab”, “a”, “ems”]Returned value: 2Explanation:…

Python question Analysis: Invariants (Q16-17) For each of the following functions, identify the loop invariant, exit condition and post condition. Question 16 (Invariant 1) This function returns the list of integers that are multiples of both 3 and 7 that occurs within a given list. Identify the loop exit condition, the loop post-condition, and the loop invariant at the end of the loop, which shows the algorithm’s correctness. def multiples_count(lst): """ Input: a list of integers, lst Output: the list of integers in lst that are multiples of both 3 and 7 """ res = [] for i in range(len(lst)): if lst[i]%3 == 0 and lst[i]%7 == 0: res.append(lst[i]) # Identify the loop invariant here return res Question 17 (Invariant 2) This function checks if a given list (of comparable elements) is sorted in ascending order.

*Data Structures and Algorithm Sliding (or k 2 − 1) puzzle using A* algorithm A sliding puzzle is a puzzle that challenges a player to slide flat pieces along certain routes on a k × k board to establish a certain end-configuration. The fifteen puzzle is the oldest type of sliding block puzzle and it was invented by Noyes Chapman in 1880s. It is played on a 4-by-4 grid with 15 square blocks labeled 1 through 15 and a blank square. The goal is to rearrange the blocks so that they are in order, using as few moves as possible. Blocks are permitted to be slid horizontally or vertically into the blank square. Search time for the goal state can be shortened by adding a priority for the direction of the search to proceed. A* algorithm is commonly used as an efficient alternative to find an answer to the sliding puzzle with the minimum number of steps. you will implement A* algorithm to solve the sliding puzzle problem. A* Algorithm A* (pronounced A-star) is an informed search algorithm,…
