Chapter 22, Problem 22.16PE

(Linear search animation) Write a program that animates the linear search algorithm. Create an array that consists of 20 distinct numbers from 1 to 20 in a random order. The array elements are displayed in a histogram, as shown in Figure 22.12. You need to enter a search key in the text field. Clicking the Step button causes the program to perform one comparison in the algorithm and repaints the histogram with a bar indicating the search position. This button also freezes the text field to prevent its value from being changed. When the algorithm is finished, display the status in the label at the top of the border pane to inform the user. Clicking the Reset button creates a new random array for a new start. This button also makes the text field editable.

Lottery Number Generator: 2.) 2.) Design a program that generates a 7-digit lottery number. The program should have an INTEGER array with 7 elements. Write a loop that steps through the array, randomly generating a number in the range of 0 through 9 for each element. Then write another loop that displays the contents of the array. All programming is in Python.
|(1st part) You are going to draw flowers a certain integral locations on a wall in your room. You have an array that stores the location of each flower as an integer. You want to better imagine how the wall will look with the drawn flowers. To do this you will create an array that will be as long as necessary to draw all the flowers. The array generated will be 1 if a flower is to be drawn at the location and 0 otherwise. Write a section of code that dynamically creates an array of the drawn flowers, based on the length of and the values of a given location array For example draw(6, {1,5,7}) should return {0,1,0,0,0,1,0,1 int draw (int length, int * location) }
2. Lottery Number Generator Design a program that generates a 7-digit lottery number. The program should have an Integer array with 7 elements. Write a loop that steps through the array, ran- domly generating a number in the range of 0 through 9 for each element. (Use the random function that was discussed in Chapter 6.) Then write another loop that displays the contents of the array.
