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.…
Art.java In this part you will create a program Art.java that produces a recursive drawing of the design attached in the picture. Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Optionally, you may use the Transform2D library you implemented in Part 1. You may also define additional geometric transforms in Art.java, such as sheer, reflect across the x- or y- axis, or rotate about an arbitrary point (as opposed to the origin). Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. call…
CSCI 2436:01L Data Structures Lab Lab 1 - Chapter 4 The Efficiency of Algorithms In this lab, you will practice how to measure the running time f a section of code in Java. One approach is to use System.nano Time() where the current time is stored as a long integer equals to the number of nanoseconds. By subtracting the starting time in nanoseconds from the ending time in nanoseconds, you get the run time-in nanoseconds of a section of code. public static void main(String[] args) { int n1 = 10, n2 = 100, n3 = 1000, n4 = 10000; long n1Time, n2Time, n3Time, n4Time; n1Time AlgorithmA (nl); For example, suppose that AlgorithmA is the name of a method you wish to time. The following statements will compute the number of nanoseconds that AlgorithmA requires to execute: } public static long AlgorithmA (int n) { long startTime, endTime, elapsedTime; startTime = System.nanoTime (); int sum = 0; for (int i = 1; i 0 1 2.

Computer Science using java The program has to evaluate arithmetic expressions using a BST for thatpurpose. The rules are the following:The program asks the user to enter an arithmetic expression in the infixformat. Then the program builds a BST for that expression. After buildingthe BST, a menu will be present to the user allowing him to: traverse the BST in inorder, traverse the BST in postorder, traverse the BST in preorder.Users will choose among the options present. The result will be thedisplay of the original arithmetic expression and the new one thatdepends on the option chosen. The program should repeat as long as theuser wants.

Note: Please answer the question in C++ only: Rajesh recently revamped its practice page to make it easier for users to identify additional problems to solve by introducing some new features: Recent Contest Problems - contains only problems from the last 2 contests Separate Un-Attempted, Attempted and All cards Problem Difficulty Rating - The Featured drop-down menu has different difficulty ranges so you can try problems that best suit your experience. Popular topics and brands Like most users, Chef didn't know that he could add problems to his personal to-do list by clicking the magic "+" symbol in the upper right corner of each problem page. But once he found out about it, he went crazy and added a lot of problems to his to-do list without looking at their difficulty rating. Rajesh is a beginner and ideally should only try to solve problems strictly below 10001000. Given the difficulty rating list of problems in Chef's to-do list, please help him determine how many of these problems…
