Problem Title : Visible Trees
There is a legend about a magical park with N × N trees. 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. A tree X is visible if all other trees in front of the tree X are shorter than the tree X.
For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4
On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees.
On the second column, Bunga can see…

- 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.arrow_forwardTreasure Hunter description You are in front of a cave that has treasures.

Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.arrow_forward
- part a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)arrow_forwardRotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]arrow_forwardHomework - identical arrays for one-dimensional: Write a test program which prompts a user to enter the size of two arrays as well as to fill their elements. After that, the program checks the same contents of the elements of the two arrays. If these arrays are equal, the program displays message which is "The two arrays are identical". If not equal, displaying "The two arrays are not identical". Write an equals method that reads two arrays and displays these messages above.arrow_forward

Given a list of rectangular towers as tuples (s, e, h) where s and e are the start and end x-coordinates (satisfying e>s) and h is the height of that tower, compute and return the total visible area of the towers, being careful not to double count two or more towers that are partially overlapping. All towers share the same flat ground baseline at the height. The classic solution illustrates the important sweep line technique that starts by creating a list of precisely those x-coordinate values where something relevant to the problem takes place. In this problem, the relevant x-coordinates are those where some tower either…arrow_forward
