Write a SuffixArray client that, given a string and an
integer L, finds all repeated substrings of length L or more.(Please give solution in java)

Using Java

Write a program that reads a file of numbers of type int and outputs all of those numbers to another file, but without any duplicate numbers. You should assume that the input file is sorted from smallest to largest with one number on each line. After the program is run, the output file should contain all numbers that are in the original file, but no number should appear more than once. The numbers in the output file should also be sorted from smallest to largest with one number on each line.

Your program should not assume that there is a fixed number of entries to be read, but should be able to work with any number of entries in both the input and output files.

This means that you should not use arrays, lists, arraylists,
linked lists, sets, maps, trees, or any other multi-element data structure.

Instead, your program should read in and write out numbers from the input and output files at the same time, eliminating duplicates from the output file as you go.

Your program should obtain both file names from the user. For the original (input) file, create a text file that stores one number per line with several duplicates in sorted order. The output file should be created by your program. When completed, your program should display on the console:

Example:

  Input File             Output File  
  Contents               Contents
     1                      1
     3                      3
     3                      60
     3                      75
     60                     80
     60                     100
     75                     130
     75                     140
     75                     985
     80                     1000
     80
     100
     130
     140
     985
     985
     985
     1000

Sample console dialog, where input from the user is underlined in italics

Propose two strategies that can be implemented in BCP to reduce the down time and improve the resistance of IT infrastructure

A company needs calculating the total working time of employees in a team. You are going to help to write a program that totals the working time in hours and minutes.   You should name your program as workingTime.py.
Your program should first ask the user how many employees there are on the team. You may assume the value entered will not be negative, but it could be zero. Your program will now be controlled by a loop that asks for, and adds, the hours and minutes for each employee. Of course the minutes will frequently add up to more than an hour, but you should not report a total time such as 24 hours 77 minutes for example (or worse, 18 hours 377 minutes). Instead you should report the total time as 25 hours 17 minutes . On the other hand, if the total number of hours is 24 or greater you should not report the time in days, hours and minutes.   Hours and minutes are all that are to be reported.

While you may assume that all of the hours and minutes entered by the user will be nonnegative, a time may be entered with minutes that exceed 60. Your program should be able to handle this and still report the total correctly. For example, 5 hours, 65 minutes and 3 hours, 88 minutes should add up to 10 hours, 33 minutes. Consequently for a given team we should see output such as:

Total time: 29 hours 18 minutes

Note:     1. The number 29 and 18 is calculated based on the user’s input.
2. If you already know about conditionals, you may not use them in this program.

In part II, the company needs to calculate the total working time for employees from all teams in days, hours, and minutes. Users of the program report that they do not like having to start the program over and over to process multiple teams, so we are going to fix that complaint.   

Add code to first ask how many teams are to be processed (you may assume the value entered is non-negative). Use this number to determine how many times the program will go through one loop (known as an outer loop) that contains within it the code from part 1. Since the loop from the code of part 1 will now lie within the loop you are developing for this part of the assignment, it is known as the inner loop. At the end of each pass of the outer loop your program should identify the team being processed as Team1, Team2, etc. and then report the total time of that Team. Thus we may see output such as:

Team1 Total time: 29 hours 18 minutes
Team2 Total time: 27 hours 49 minutes
Team3 Total time: 15 hours 1 minutes

Finally, add code to output the total time of all of the teams entered. Thus, the last line of output may be: Total time of all teams: 3 days 0 hours 8 minutes Note that the total time for all teams should display the number of days, hours, and minutes.

If you already know about conditionals, you may not use them in this program.

Abstraction is the basis for good Object-Oriented design that is modular, reusable, and maintainable.

Interfaces and Abstract classes are two mechanisms in Java that provide high-level abstractions. An interface or abstract class is something which is not concrete, something which is incomplete.

For this discussion, what do you think is meant by “Programming to an interface”? What are some differences between Abstract Classes and Interfaces? Provide a simple example application with an interface definition and a class which implements the interface.

The Lo Shu Magic Square is a grid with 3 rows and 3 columns. The Lo Shu Magic Square has the following properties:

The grid contains the numbers 1 through 9 (each number only once)

The sum of each row, each column and each diagonal are the same

In a program you can simulate a magic square using a two-dimensional array. Write a method that accepts a two-dimensional array as an argument, and determines whether the array is a Lo Shu Magic Square. Test the function in a program.

Detailed Description:

In main create two arrays:

// Create a magic two-dimensional array.

      int[][] magicArray = { {4, 9, 2},

                             {3, 5, 7},

                             {8, 1, 6} };

      // Create a normal two-dimensional array.

      int[][] normalArray = { {1, 2, 3},

                              {4, 5, 6},

                              {7, 8, 8} };

For the normalArray call showArray and then showResult. Then do the same for magicArray

showArray accepts a two-dimensional array and prints it row by row

showResult call isMagicSquare with the two-dimensional array reference as the parameter. It prints a message based on the return value which is Boolean.

The isMagicSquare method accepts a two-dimensional int array as an argument, and returns true if the array meets all the requirements of a magic square. Otherwise it returns false. You can create separate methods to checkRange (all must be from 1-9), checkUnique (see if all values are unique), checkRowSum, checkColSum, checkDiagSum. If each of these 3 return true then it is a Magic Square.

Output should be

1 2 3

4 5 6

7 8 8

This is not a Lo Shu magic square.

4 9 2

3 5 7

8 1 6

This is a Lo Shu magic square.

With four Boolean inputs mentioned in the first four columns of the following table, report the outputs from the circuits described by the Boolean expressions in the topmost row of the table in the 5^th and 6^th columns, in the corresponding rows in the 5^th and 6^th columns of the table. The circuit in the 5^th column uses two AND gates, two NOT gates, and one OR gate. The circuit in the 6^th column uses two AND gates and one OR gate. You can draw the circuits or construct partial truth tables which have just the given combinations of input values instead of the 16 possible combinations, if you wish. You can also find the answers by simply using the meaning of AND, OR, and NOT gates.

c. In your own words, define "mutual recursion" as it pertains to C++ programming.

Write a program that creates a two-dimensional array initialized with test data. Use any

primitive data type that you wish. The program should have the following methods:

• fillRandom. Accepts a reference to a two-dimensional array and fills it with random integers from 0 to 99
• formatPrint. This method should accept a two-dimensional array and print it out row by row
• getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array.
• getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. Calls getTotal and getElementCount.
• getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the sub- script of a row in the array. The method should return the total of the values in the specified row.
• getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column.
• getHighestInRow. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the highest value in the specified row of the array.
• getLowestInRow. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the sub- script of a row in the array. The method should return the lowest value in the specified row of the array.
• getElementCount. This method should accept a two-dimensional array and returns the total number of elements in the array.

Demonstrate each of the methods in this program. Each (except for getElementCount, are called from main.

The main program will request the number of rows and columns as input, creates the two-dimensional array, and first calls fillRandom. A sample output is:

Please enter the number of rows and columns in a two dimensional array: 4 5

78 65 72 30 95

60 71 88 41 73

32 74 47 70 27

59 91 80 81 87

Output:
Processing the int array.
