- in c++ using 2D Arrays The following diagram represents an island with dry land (represented by “-“) surrounded by water ((represented by “#“). ##-########## #-----------# #-----------# #------------ # -----------# #------X----# #-----------# ############# Two bridges lead off the island. A mouse (represented by “X”) is placed on the indicated square. Write a program to make the mouse take a walk across the island. The mouse is allowed to travel one square at a time, either horizontally or vertically. A random number from 1 to 4 should be used to decide which direction the mouse is to take; for the sake of uniformity assume that 1 = up, 2 = down, 3 = left, and 4 = right. Since the mouse is wearing cement mouse galoshes, the mouse drowns when he hits the water. He escapes when he steps on a bridge. You may generate a random number up to 100 times allowing the mouse to take 100 steps. If the mouse does not find a bridge by the 100th try, he will wither away and die of starvation.…b.

- Please help me with this code, Im am confused adn dont know where to start. Develop a high-quality, menu-driven object-oriented C++ program that creates a small database, using a binary search tree structure to store and process the data. The database will contain the top 100 highest grossing films of 2017. The C++ object-oriented program must use the BinarySearchTree class When designing and implementing the program, apply good software engineering principles. Your program must include: a Film class that stores all the data for a Film and provides appropriate methods to support good software engineering principles, a FilmDatabase class that stores the binary search tree and provides appropriate methods in support of database queries and reporting using good software engineering principles, an application that interacts with the end-user. The design is up to you and may include any number of classes in support of the given application. A Menu class is strongly recommended.…Python Need help with code A rule has three parts: •name –a simple name for the rule (e.g., up, left, down, right) •precondition function –a Boolean function that accepts a state and returns true if the rule is applicable to state •action function –a function that accepts a state and returns the successor state obtained by applying the rule. You can use these rules to implement functions such as applicable-rule, which returns a list of the rules applicable to a given state, and successor-state, which returns the successor state for a given state and rule. Question: Encode the rules for the sliding-tile puzzle. Remember that it is easiest to consider moving the empty space up, left, down, or right. Using these rules, write routines to determine the rules applicable to a state and the successor state given a state and rule to apply. Note that you could implement these as iterators or have them return lists (or vectors) or rules and states.Movie search system that displays actors and information about the movie. If you search for an actor, it should show you her or his movies. This can be in C++ and must use a data applied structure such as bubble sort or graph wise or using BTS.
