Exercise 3: Multiple Scatter plots Generate scatter plots between every pairs of numerical columns from the "iris" dataframe as a set of subplots

Let N be an unordered array of integers. The maximum number of compares required to find the minimum value is N. Select one  True or False

What is the run-time complexity for inserting an item when the insertion point is the logical size of the array.

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.,…
