Chapter 7, Problem 7.33RE
(Maze Traversal) The grid of hashes (#) and dots (.) in Fig. 7.27 is a two-dimensional built in array representation of a maze. In the two-dimensional built-in array, the hashes represent the- walls of the maze and the dots represent squares in the possible paths through the maze Moves can be made only to a location in the built-in array that contains a dot.
There is a simple
Fig 7.27 Two-dimensional built-in array representation of a maze.
Write recursive function mazeTraverse to walk through the maze. The function should receive arguments that include a 12-by-12 built-in array of chars representing the maze and starting location of the maze. As mazeTraverse attempts to locate the exit from the maze, it should place the character X in each square in the path. The function should display the maze after each move, so the user can watch as the maze is solved.

Question 4: (30 marks) A Math teacher is teaching Math course to a set of classes (each class may have different number of students) and want to check the behavior of his students in a homework report. The teacher gave the classes the same exam and marked their answer and wants to know the class whose students got the highest average. Help the teacher in the required analysis of student’s marks by implementing a Java program ClassAverageMArks2DimmArray using 2-dimensional array to store the students marks and then compute the average of each class student’s marks. The program has the following specification: • A Method titled averageClassMarks for computing the average (as double) of a class students marks (given to the method as a single-dimensional array) • Another Method titled averageAllClassesMarks for computing the average (as single array of double) of all the classes class student’s marks (given to the method as a 2dimensional array). This method has to repeatedly call the…

2: (Knapsack Problem) Using exhaustive search, find the most valuable subset of items
that fit into the knapsack if the knapsack capacity is 10kg. Since it is exhaustive search,
you need to show all possible options of picking the objects, calculate the value for
each, mark those which are not feasible, and pick the best.

Of course, which lights were on the first night and which were not. Every other night the condition of the lamps shall be determined by the following rules: the lamp will not illuminate if both of its neighbors were lit last night; the lamp shall illuminate if one of its neighbors was illuminated last night and the other was not; if neither of the first two rules applies to the lamp, it will illuminate when the night is even and will not illuminate when the night is odd. Create a program to determine which lights are on and which will not be lit when k (1 < k < 100) nights have elapsed, and to find which night the most lights were lit and which the least.

The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row.

- Exercise 1: (Design of algorithm to find greatest common divisor) In mathematics, the greatest common divisor (gcd) of two or more integers is the largest positive integer that divides each of the integers. For example, the gcd of 8 and 12 is 4. Why? Divisors of 8 are 1, 2, 4, 8. Divisors of 12 are 1, 2, 4, 6, 12 Thus, the common divisors of 8 and 12 are 1, 2, 4. Out of these common divisors, the greatest one is 4. Therefore, the greatest common divisor (gcd) of 8 and 12 is 4. Write a programming code for a function FindGCD(m,n) that find the greatest common divisor. You can use any language of Java/C++/Python/Octave. Find GCD Algorithm: Step 1 Make an array to store common divisors of two integers m, n. Step 2 Check all the integers from 1 to minimun(m,n) whether they divide both m, n. If yes, add it to the array. Step 3 Return the maximum number in the array.arrow_forward9.
