Question
Union-Find: Maze
Write a program that generates mazes of arbitrary size using the union-find algorithm . A
simple algorithm to generate the maze is to start by creating an N x M grid of cells separated by
walls on all sides, except for entrance and exit. Then continually choose a wall randomly, and
knock it down if the cells are not already connected to each other. If we repeat the process until
the starting and ending cells are connected, we have a maze. It is better to continue knocking
down the walls until every cell is reachable from every cell as this would generate more false
leads in the maze.
Test you algorithm by creating a 15 x 15 grid, and print all the walls that have been knocked
down. D

- In PYTHON use a Monte Carlo Simulation to write a code that gives the probability that in a classroom of x people, at least 2 will be born on the same day of the year, ignoring leap year? The number of people in the class is given by the user as variable x. Here is the code outline that is needed to answer this question. Please use it in your answer: import mathimport random # create and initialize frequency table:ft = []k = 0while(k < 365) : ft.append(0) k = k+1 # Allow the user to determine class size:print("Please type in how many people are in the class: ")x= int(input()) success = 0 # Simulate:c = 0while(c < 10000) : # Step 1: re-initialize birthday frequency table (it must be re-initialized for each play-through (why?): k = 0 while(k < 365) : ft[k] = 0 k = k+1 # Step 2: randomly get x birthdays and update frequency table: k = 0 while(k < x): # your code goes here ########################## k = k+1 # Step 3: Check to see if this...arrow_forwardLab Goal : This lab was designed to teach you more about recursion. Lab Description : Take a number and recursively determine how many of its digits are even. Return the count of the even digits in each number. % might prove useful to take the number apart digit by digit Sample Data : 453211145322224532714246813579 Sample Output : 23540arrow_forwardA popular word game involves finding words from a grid of randomly generatedletters. Words must be at least three letters long and formed from adjoining letters.Letters may not be reused and it is valid to move across diagonals. As an example,consider the following 4 * 4 grid of letters: A B C DE F G HI J K LM N O P The word "FAB" is valid (letters in the upper left corner) and the word "KNIFE"is valid. The word "BABE" is not valid because the "B" may not be reused. Theword "MINE" is not valid because the "E" is not adjacent to the "N". Write a program that uses a 4 * 4 two-dimensional array to represent the gameboard. The program should randomly select letters for the board. You may wishto select vowels with a higher probability than consonants. You may also wish toalways place a "U" next to a "Q" or to treat "QU" as a single letter. The programshould read the words from the text file words.txt (included on the website withthis book) and then use a recursive algorithm to...arrow_forward
