can you please convert this python code into java? Python code is as shown below: #recursive function def row_puzzle_rec(row, pos, visited): # if the element at the current position is o we have reached our goal if row[pos] == 0: possible = True else: # make a copy of the visited array visited visited[:] # if the element at the current position has been already visited then it's a loop. # as then its not possible to reach the last element, set possible to False if visited[pos]: possible = False else: #set visitied for the element as True visited[pos] = True possible = False # if its possible to move left then recurse in the left direction if pos - row[pos]>o and row_puzzle_rec(row, pos - row[pos], visited): # return immediately if the goal is reached return True # if its possible to move right then recurse in the right direction if pos + row[pos] < len(row) and row_puzzle_rec(row, pos + row[pos], visited): # return immediately if the goal is reached. return True return possible def row_puzzle(row): #visited array will be used to check if a particular element was visited # initialize the array to False visited - [False for item in range(len(row))] #second argument is the token position initialized to o return row_puzzle_rec(row, o, visited) possible row_puzzle([2, 4, 5, 3, 1, 3, 1, 4, 0)) print(possible) possible = row_puzzle([1, 3, 2, 1, 3, 4, ol) print(possible)

I need matlab codes please. the one in blue box is the answer and also I need the graph.

2. (a) Compute and simplify f = (xz+ (y+t)' + (xz)'y')' Encircle final answer! (b) Prove or disprove that in any Boolean algebra, B: (i) 0' = 1 (ii) 1' = 0

2. calculates the trajectory r(t) and stores the coordinates for time steps At as a nested list trajectory that contains [[xe, ye, ze], [x1, y1, z1], [x2, y2, z2], ...]. Start from time t = 0 and use a time step At = 0.01; the last data point in the trajectory should be the time when the oscillator "hits the ground", i.e., when z(t) ≤ 0; 3. stores the time for hitting the ground (i.e., the first time t when z(t) ≤ 0) in the variable t_contact and the corresponding positions in the variables x_contact, y_contact, and z_contact. Print t_contact = 1.430 X_contact = 0.755 y contact = -0.380 z_contact = (Output floating point numbers with 3 decimals using format (), e.g., "t_contact = {:.3f}" .format(t_contact).) The partial example output above is for ze = 10. 4. calculates the average x- and y-coordinates 1 y = Yi N where the x, y, are the x(t), y(t) in the trajectory and N is the number of data points that you calculated. Store the result as a list in the variable center = [x_avg, y_avg]...

EXAMPLE: The sum of any two even integers is even. Answer: Proof. (direct) Suppose x and y are even integers. By definition of even, let x = 2k and y = 2j for some integers j and k. Then, x+y=2k+2j = 2(k + j) Note that k+j is an integer because it is the sum of integers. Therefore, by definition of even, x + y is even.
