4.7 Code Practice: Question 1 Please help!

Suppose you are in charge of unloading containers from ships arriving at a port onto trucks. A ship arrives with n containers of weight w1, w2, . . . , wn tons. Standing on the dock is a set of trucks, each of which can hold 1 ton of weight. (You can assume that none of the containers weighs more than 1 ton, since in this case you would not be able to transport it.) You can stack multiple containers in each truck subject to the weight restriction of 1 ton. Hoping to minimize your truck rental expenses, you aim to minimize the number of trucks needed in order to carry all the containers.

You start with the following greedy strategy. Start with an empty truck and begin loading containers 1, 2, 3, ... onto it until you get to a container that would overflow the weight limit. Now, declare this truck "loaded" and send it off; then continue the process with a fresh truck. After trying (and failing) to prove that this greedy algorithm is optimal, you decide to attempt to come up with a counter-example to see if you can discover that your strategy is not optimal.

Required:
Provide an example of a set of weights for which your algorithm does not use the minimum possible number of trucks.

Steve Jobs


Born

Death

Steven Paul Jobs was an American inventor, designer and entrepreneur who was the co-founder, chief executive and chairman of
Apple Computer.

Apple Computer

In 1976, when Jobs was just 21, he and Wozniak started Apple Computer in the Jobs’ family garage. They funded their entrepreneurial
venture by Jobs selling his Volkswagen bus and Wozniak selling his beloved scientific calculator. Jobs and Wozniak are credited with
revolutionizing the computer industry with Apple by democratizing the technology and making machines smaller, cheaper, intuitive and
accessible to everyday consumers.

Wozniak conceived of a series of user-friendly personal computers, and — with Jobs in charge of marketing — Apple initially marketed
the computers for $666.66 each. The Apple I earned the corporation around $774,000. Three years after the release of Apple's second
model, the Apple II, the company's sales increased by 700 percent to $139 million.

In 1980, Apple Computer became a publicly-traded company, with a market value of $1.2 billion by the end of its very first day of
trading. Jobs looked to marketing expert John Sculley of Pepsi-Cola to take over the role of CEO for Apple.

The next several products from Apple suffered significant design flaws, however, resulting in recalls and consumer disappointment.
IBM suddenly surpassed Apple in sales, and Apple had to compete with an IBM/PC-dominated business world.

In 1984, Apple released the Macintosh, marketing the computer as a piece of a counterculture lifestyle: romantic, youthful,
creative. But despite positive sales and performance superior to IBM's PCs, the Macintosh was still not IBM-compatible.

Sculley believed Jobs was hurting Apple, and the company's executives began to phase him out. Not actually having had an
official title with the company he co-founded, Jobs was pushed into a more marginalized position and thus left Apple in 1985.

Write a program to grade an n-question multiple-choice exam (for n between 5 and 50) and provide feedback about the most frequently missed questions. Your program will take data from the file examdat.txt. The first line of the file contains the number of questions on the exam followed by a space and then an n-character string of the correct answers. Write a function fgets Answers that inputs the answers from an open input file. Each of the lines that follow contain an integer student ID followed by a space and then that stu dent's answers. Function fgets Answers can also be called to input a student's answers. Your program is to produce an output file, report.txt, containing the answer key, each student's ID, and each student's score as a percentage, and then information about how many students missed each question.
