Why has governmental crime been relatively neglected by criminologists?

Plan production for a four-month period: February through May. For February and March, you should produce to exact demand forecast. For April and May, you should use overtime and inventory with a stable workforce; stable means that the number of workers needed for March will be held constant through May. However, government constraints put a maximum of 5,000 hours of overtime labor per month in April and May (zero overtime in February and March). If demand exceeds supply, then backorders occur. There are 100 workers on January 31. You are given the following demand forecast: February, 80,256; March, 70,400; April, 100,360; May, 40,360. Productivity is four units per worker hour, eight hours per day, 22 days per month. Assume zero inventory on February 1. Costs are hiring, $45 per new worker; layoff, $65 per worker laid off; inventory holding, $10 per unit-month; straight-time labor, $10 per hour; overtime, $15 per hour; backorder, $20 per unit.

Develop a production plan and calculate the total cost of this plan. Note: Assume any layoffs occur at beginning of next month. (Leave no cells blank - be certain to enter "0" wherever required. Negative values should be indicated by a minus sign. Round your answers to the nearest whole number.)

The King of Sharks: A Native American Myth from Hawaii retold by S. E. Schlosser One day, the King of Sharks saw a beautiful girl swimming near the shore. He immediately fell in love with the girl. Transforming himself into a handsome man, he dressed himself in the feathered cape of a chief and followed her to her village. The villagers were thrilled by the visit of a foreign chief. They made a great luau, with feasting and games. The King of Sharks won every game, and the girl was delighted when he asked to marry with her. The King of Sharks lived happily with his bride in a house near a waterfall. The King of Sharks, in his human form, would swim daily in the pool of water beneath the falls. Sometimes he would stay underneath the water so long that his bride would grow frightened. But the King of Sharks reassured her, telling her that he was making a place at the bottom of the pool for their son. Before the birth of the child, the King of Sharks returned to his people. He made his wife swear that she would always keep his feathered cape about the shoulders of their son. When the child was born, his mother saw a mark upon his back which looked like the mouth of a shark. It was then she realized who her husband had been. The child's name was Nanave. As he grew towards manhood, Nanave would swim daily in the pool beside the house. Sometimes, his mother would gaze into the pool and see a shark swimming beneath the water. Each morning, Nanave would stand beside the pool, the feathered cloak about his shoulders, and would ask the passing fishermen where they were going to fish that day. The fisherman always told the friendly youth where they intended to go. Then Nanave would dive into the pool and disappear for hours. The fishermen soon noticed that they were catching fewer and fewer fish. The people of their village were growing hungry. The chief of the village called the people to the temple. "There is a bad god among us," the chief told the people. "He prevents our fishermen from catching fish. I will use my magic to find him." The chief laid out a bed of leaves. He instructed all the men and boys to walk among the leaves. A human's feet would bruise the tender leaves, but the feet of a god would leave no mark. Nanave's mother was frightened. She knew her son was the child of a god, and he would be killed if the people discovered his identity. When it came turn for the youth to walk across the leaves, he ran fast, and slipped. A man caught at the feathered cape Nanave always wore to prevent him from being hurt. But the cape fell from the youth's shoulders, and all the people could see the shark's mouth upon his back. The people chased Nanave out of the village, but he slipped away from them and dived into the pool. The people threw big rocks into the pool, filling it up. They thought they had killed Nanave. But his mother remembered that the King of Sharks had made a place for her son at the bottom of the pool, a passage that led to the ocean. Nanave had taken the form of a shark and had swum out to join his father, the King of Sharks, in the sea. But since then, the fishermen have never told anyone where they go to fish, for fear the sharks will hear and chase the fish away.

TITLE

PRIME FACTORIZATION USING AN ARRAY-BASED STACK

INTRODUCTION

This project revisits one of the problems in Project 2, and it will re-use a function within the solution developed there.

An integer is prime if it is divisible only by itself and 1. Every integer can be written as a product of prime numbers, unique except for their order, called its prime factorization. For example,

1776 = 37 x 3 x 2 x 2 x 2 x 2.

DESCRIPTION

Design, implement, document, and test an interactive program that reads positive integers from the terminal and writes their prime factorizations to the screen. The program should list the factors of each integer in decreasing order, as in the example above, and should terminate when the user enters 0 or a negative value.

INPUT

The program's input is positive integers, entered from the terminal, terminated by 0 or a negative value.

OUTPUT

The program's output consists of prompts for the input values and the input values' prime factorizations. It writes this output to the terminal.

ERRORS

The program can assume that its input is integers; it need not detect any errors.

EXAMPLE

A session with the program might look like this:

  Enter a positive integer (0 to stop): 1776
    Prime factors: 1776 = 37 x 3 x 2 x 2 x 2 x 2

  Enter a positive integer (0 to stop): 6463
    Prime factors: 6463 = 281 x 23

  Enter a positive integer (0 to stop): 349856
    Prime factors: 349856 = 29 x 29 x 13 x 2 x 2 x 2 x 2 x 2

  Enter a positive integer (0 to stop): 36423479
    Prime factors: 36423479 = 36423479

  Enter a positive integer (0 to stop): 1
    Prime factors: 1 = 1

  Enter a positive integer (0 to stop): 0
    

OTHER REQUIREMENTS

Implement a stack abstract data type in a class in which a typedef statement specifies the type of the stack's items. Use a sequential (array-based) stack implementation. As the program identifies prime factors, it should save them by pushing them onto a stack of integers provided by this class.

If d >= 2 is the smallest integer that divides an integer n, then d is prime. Therefore the program can identify prime factors (in ascending order) by repeatedly identifying the smallest factor of the target value and then dividing the target value by the factor. The program need not test that these smallest factors are prime or attempt to list only prime values; this will happen automatically.

Thus, to identify the prime factors of n, first find the smallest factor that divides n, push it onto the stack, and divide n by the factor. Then find the smallest factor of the new value of n; handle it the same way. Continue in this way until n = 1. Then pop and print the values until the stack is empty.

This scheme identifies prime factors in order of increasing magnitude; saving the values on the stack and then popping and printing them displays them in decreasing order, as specified.

HINT

Recall that you wrote a function that returns the smallest factor of its positive integer argument back in Project 2. You can re-use that function in this project.

HAND IN

See About Programming Assignments for a description of what to hand in: design document, user document, code, tests, and summary.

Question: If we wanted to report each integer's prime factors in increasing order, would the stack be necessary or helpful? Explain.

Project 2:

PRIME FACTORIZATION

The smallest nontrivial factor of a positive integer is necessarily prime. (Can you prove this?) Write a program that takes advantage of this fact in a recursive function that writes the prime factors of an integer to the terminal in ascending order.

A run of the program that exercises this function might look like this:

          Enter a positive integer: 5432
          The prime factors of 5432 are 2 2 2 7 97
    

Hint: Begin by writing a function that returns the smallest factor (greater than 1) of its positive integer argument. The recursive function will call this one.

QUESTION: How would you modify the function to print the prime factors in descending order?
