(Duplicate Elimination) Use a one dimensional array to slove the following problem. Read 20 numbers, each of which is 10 and 100, inclusive. As each number is read, print it only if it's not a duplicate of a number already read. Provide for the "worst case" in which all 20 numbers are different. use the smallest possible array to slove this problem.

Add the following functionality to your solution. Sort the array in ascending order and print the elements of the sorted array.

if you could please explain each line of the code that would be wonderful.

For each of the following statements, state whether the statement is true or false AND justify your answer.

1. 2. When a map-reduce job is running on Hadoop, the number of map tasks must be equal to the number of reduce tasks because each map task feeds its output to a specific reduce task.
2. 4. In order to guarantee the scalability of the system, each file block is replicated three times in Hadoop distributed file system (HDFS).
3. 5. When a map-reduce job is submitted to Hadoop, the first step is to shuffle and sort the input key/value pairs so that each input key is assigned to a map task.

How do we separate end-users security policies from the infrastructure security policies on the windows server?

Computer Architecture:

Write a MIPS program to compute f = g - (f + 5)
Assume registers $to, $s1 hold values for g and f respectively.
The program should display the following prompts and read value entered by the user “Enter a value for f:"
“Enter a value for g:"
The program the prints: "Answer for f = g - (f + 5):"
The program should repeat the above steps 3 times for each input pair, f and g

Make certain that your assembly code is properly organized (indented, commented, contains your name at the top of the code). Comment any assumptions at the top and include results showing the working code via screen prints

1. The community college you work for would like to get a security test performed, explain the different test types and the advantages and disadvantages of them

.2. The community college now wants to have a security company come in and perform security tests. Explain what they should expect before, during, and after the testing.

You have been hired by a home security company to design and implement a home alarm system. The logic of the system is as follows: once the alarm system has been armed, it is to sound if the front door is opened, the back door is opened or either of two windows is opened (you can assume there are only two windows).

Design the necessary circuit to implement the situation described above. Your circuit should have five inputs (A = alarm, F = front door, B = back door, W1 = window 1 and W2 = window 2). A = 1 means the system is armed; A = 0 means it is disarmed. F = 1 means the front door is open; F = 0 means it is closed. (Similarly for the back door and the windows.) There should be one output, S. When S = 1 the alarm should sound; S = 0 means the alarm is silent. Please use these letters to indicate the inputs and the output so all projects are consistent.

Be CAREFUL to get the correct function for your five inputs before simplifying and designing the circuit. You should minimize the circuit. Your inputs and output should be labeled. You should submit a Microsoft Word document including the following items while ensuring that everything is laid out in a manner that is easy to follow (portrait or landscape is acceptable):

• Your name in the top left

• Drawing of your completed circuit including all appropriate labels.

You will need to practice your MS Word drawing, layering, and object management skills.

See below for common logic gate objects that can be reused in your document.

• Truth tables for the circuit (use Word table feature)

• Kmap for the circuit (use Word table feature)

• Details (show your work) on what was done to simplify the circuit

• A brief written summary (250 to 500 words) of the process you followed, decisions made in laying out the circuit, etc..

Climbing Stairs

Bibi climbs stairs of a multi-leveled building. Every time Bibi climbs a set of stairs, she counts the steps starting from 1 to the number of steps in that particular set of stairs while climbing the stairs. For example if she climbs two set of stairs, the first containing 5 steps and the second containing 3 steps, she will say 1, 2, 3, 4, 5, 1, 2, 3 and the total number of steps would be 8. Find the number of steps that Bibi climbed in each set of steps.

Format Input:

The first line of the input contains an integer N, the number of numbers Bibi said. The second line of the input contains N integers Ai , the i-th number Bibi said. The given sequence of Ai will be a valid sequence, that means the whole input can be cut into sequences of 1, 2, . . . , X, where X is the number of steps in a set of stairs.

Format Output:

Print the number of steps that Bibi climbed for each set of steps, in the order of the input sequence, separated by single spaces. There is no leading and trailing spaces in the output.

Constraints

• 1 ≤ N ≤ 1, 000

• 1 ≤ Ai ≤ 1, 000

• The given sequence of Ai will be a valid sequence, that means the whole input can be cut into sequences of 1, 2, . . . , X, where X is the number of steps in a set of stairs.

Sample Input 1 (standard input):

1 2 3 4 5 1 2 3

Sample Output 1 (standard output):

5 3

Sample Input 2 (standard input):

10

1 2 1 1 2 3 4 1 2 3

Sample Output 2 (standard output):

2 1 4 3

Sample Input 3 (standard input):

1 2 3 4 5

Sample Output 3 (standard output):

5

Note The first sample is the example from the problem description.

In the second sample:

The first set of stairs have 2 steps, current sequence is ”1, 2”

second set have 1 steps, current sequence is ”1, 2, 1”

third set have 4 steps, current sequence is ”1, 2, 1, 1, 2, 3, 4”

last set have 3 steps, current sequence is ”1, 2, 1, 1, 2, 3, 4, 1, 2, 3”, just like the input

In the third sample, there is only one set of stairs which contains 5 steps.

*Note: Use C language and long long int (must be the same as the constraint)

Create a SavingsAccount class to store data of savers (account holders). Your class should match the following specifications.
1. Each instance of the class contains a private data member savingsBalance indicating the amount the saver currently has on deposit, saver’s name, saver’s CNIC, account number (this has to be unique) and a member to store saver status (if savingsBalance > 10000 then status changes to gold otherwise silver).
2. Class also has a data member annualInterestRate to store the annual interest rate which will be the same for all the savers.
3. Implement a default constructor with minimum savingsBalance of 100, and other fields as well. Also create a parameterized constructor if a customer wants to open an account with a different starting balance.
4. Provide member function calculateMonthlyInterest that calculates the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12; this interest should be added to savingsBalance.
5. Provide a recursive member function turnInToGold that returns the number of months a saver need to become gold member
6. Provide a member function modifyInterestRate that sets the annualInterestRate to a new value.
7. Provide a function that returns the total number of account holders with the bank.
8. Write main() to test class SavingsAccount . Instantiate two different objects of class SavingsAccount, s1 and s2, with balances of $2000.00 and $3000.00, respectively. Set the annualInterestRate to 3 percent. Then calculate the monthly interest and print the new balances for each of the savers. Then set the annualInterestRate to 4 percent, calculate the next Month’s interest and print the new balances for each of the savers. Also print the months it will take for both to become gold savers of bank.

Write a Java program which takes a String representing an arithmetic expression as an input and displays whether or not the expression is balanced. If the expression is not balanced (i.e. the wrong # of parentheses or in the wrong order) it will display an error message. For Example: Input an expression: ( ( 2 + 4 ) * 2 ) Expression is balanced Input an expression: ( 5 * 7 – 6 ) ) Error: Expression is not balanced.... Implement a stack calculator using both a numbers and operations stack. Be sure to check that the expression is balanced before running it through the calculator.
