You are allowed to follow a path on the 4-by-4 array of numbers below, starting on anynumber, and taking upward and downward steps, as well as steps to the left and to theright, along the way. However, you are not allowed to go diagonally, nor are youallowed to go to the same position twice. How many different ways can you get thesum of the numbers to add up to 10 by following a path on the array?| 3 1 1|31 4 4 11 4413 11|3

The total number of ways in which the array can be traversed to get the sum 10 is: 104.

Assume that you have declared a two-dimensional array to store the number of website visitors. If Sunday is the first value and Monday is the second one, choose the Java code that evaluates to the number of visitors on Monday for the last hour of the day: visitors[0] visitors[0][24] visitors[1] visitors[1], visitors[24] visitors[1][-1] visitors[1][23]
Use a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 20 and 50, inclusive. As each number is read, validate it and check its value. Numbers greater than 40 are to be stored as they are. Numbers that are less than or equal to 40 should be doubled and then stored. After reading all the values, display all the values which were stored.
You can see in the above display, we first sort each row of the 2D array; we then take the transpose of a two D array, i.e., all the row elements becoming the column elements; we then sort each row of the 2D again. If you read the final array, each row is sorted; each column is also sorted. The smallest element obviously is the 1st element of the two D array and the last element is the largest element of a two D array. Let us now look at the following UML diagram: (Note that additional methods are allowed; proposed methods and instance variable cannot be changed) Main method firstly constructs a 2D array of certain sizes and then construct a TwoD object and drive the task according to the above runtime interactions and displays. TwoD class has only one instance variable which is a two D array of numbers ( int or double). The constructor must do some “deep” copying. A copy constructor. The other three methods are obvious in definition: to sort each row, to rotate the 2D array (i.e.,…
