## Assume you have a set of cards laid out in an n by m grid (n rows of m columns each). Some are face up, and others are face down. We can collapse the grid into a single pile by using a series of flips, each of which is one of the four following types: Top Flip: Here the cards in the top row are flipped over onto the corresponding cards on the row beneath them. Note that if a card is face up in the top row, it becomes face down after the flip, and vice versa. If the top row contains one or more piles of cards, each entire pile is flipped over like a stack of pancakes as it is moved to the lower row. Note: Conceptually, we think of flipping the ENTIRE stack at once; what actually happens is that each card in the stack gets flipped one at a time, until that stack has no cards left.

Instruction

Input: Each test case will start with a line containing two positive integers n m indicating the number of rows and columns in the grid. There will be a space between n and m. After this will come n rows of m strings indicating each card’s number and its orientation. (the first row is the top row and the first value in each row is the leftmost card.) Each string will be of the format OSV, where: O is the orientation: either ‘U’ for “face-Up”, or ‘F’ for “face-Down” S is the suit: one of ‘C’, ‘D’, ‘H’, ‘S’ for “Clubs”, “Diamonds”, “Hearts”, or “Spades”, respectively V is the face Value: one of ‘2’, … ‘9’, ‘T’ (ten), ‘J’ (Jack), ‘Q’ (queen), ‘K’ (King), or ‘A’ (Ace) Thus, “USA” indicates “Ace of spaces, face-up”, and “DC3” represents “3 of Clubs, face-down” You will have to (A) make sure that each OSV string is valid, and then (B) convert each to an integer in the range of -52 to +52, representing the four suits and 13 values, with the sign representing the orientation. Zero will not be used. If a string is not valid, your program must end. Immediately, with no error message (a rather user-unfriendly and heavy-handed way of handling errors, but this program isn’t necessarily about the input’s validity so much as it is about processing the stacks. Your input must accept upper- or lower-case characters(card identification strings are not case-sensitive). After these n rows there will be one more line containing n + m – 2 characters indicating the order in which to apply the flips to the grid. Each character will be either ‘T’, ‘B’, ‘L’ or ‘R’ corresponding to a top, bottom, left or right flip. All flip sequences will be legal, i.e., you won’t be asked to do more than n – 1 top and bottom flips or m – 1 left and right flips. You are not responsible for making sure that the flip directions are one of TBLR – I won’t test your code with an illegal flip direction. The maximum value for n and m is 20. A line containing two zeros will terminate input. Obviously, if m * n is > 52, it will require more than one deck of cards. Repeated cards should be a non-issue for your program

You are just hired as a data analyst (Note1) in the newly formed analytics department of RiiiD, which is a leading AI startup company specializing in providing learning resources and adaptive practices to English learners in South Korea. On the first day of your job, you are invited to attend a meeting with the business operation team in which you are briefed on the company’s platform and then you are handed over a dataset (‘EdNet’) that was collected from this platform over the last two years from over 700K users . This dataset logged detailed user activities while they were interacting with systems. Intrigued by the sheer amount of data collected, your manager is interested in how the analytics department can help to support the company’s missions to reimagine the learner’s experience using AI/ML/data analytics techniques. You are asked to spend some time to look into the data and prepare a brief to your manager. Specifically, your manager is looking for answers to the following questions.

(25 points) Who are the users? To answer this question, you will need to compile a user profile table (Table 1) with information about users including
Create a few plots to illustrate the information in the tables. Feel free to choose the appropriate type of plots you think is appropriate.

2. (25 points) What are the questions/items? To answer this question, you will need to compile a question profile table (Table 2) with information including

a. Question ID

b. Question Type

c. Number of times being practiced

d. Number of times answered correctly

Create a few plots to illustrate the information in the tables. Feel free to choose the appropriate type of plots you think is appropriate.

3. (10 points) Design a modified metric of “accuracy” to fairly describe users’ ability by taking into account the difficulty level as derived from Table 2. Describe the procedure to compute the metrics. Be sure to be specific so that interns can use your pseudo code to implement the metrics without much trouble.

BONUS (10 points), implement the proposed metrics and plot a histogram of the metrics across all users (or subset of users of your choices).

4. (30 points) Pick a user with a reasonable amount of activity (you will define the “reasonableness” and specify the selection criteria) and create a dashboard that consists of a series of plots to tell a story of this user’s activity patterns. For inspiration, you may look at the user dashboard for fitness tracker such as Fitbit.

5. (10 points) Propose two tasks for your interns to work on. The first task is of unsupervised/descriptive type and a second one is of supervised/predictive task. Please provide clear specification of the tasks so that your interns can start to work right away. You should try to propose tasks that are not attempted in the existing work with this dataset.

BONUS (10 points): propose a reinforcement learning task

Deliverable:

A google slide deck summarizing the above findings in the format of plots or tables or other contents as requested by your manager. Please label clearly on the slide which question you are answering. There are no lower/upper limits of the number of slides. Always keep the message concise and effective and keep your audience in mind. In this case, it is your manager. Please change the slides permission to editable, we will make comments on your slides.
Two summary tables, Table 1 and 2
Please deposit the above items into your own google folder you are asked to create, under this folder, create a folder named homework1. Please deposit the files there.

Backwoods American, Inc., produces expensive water-repellent, down-lined parkas. Currently, the cost of producing each parka is estimated to be \$55. This company is planning to produce approximately 1650 parkas in the next year. The quality manager of the company has estimated that, with the current situation, 10 percent of the parkas produced will be defective and only 50 percent of the defective parkas can be reworked. The rework cost is estimated to be \$10.The quality management department has suggested to upgrade the sewing machine to reduce the percentage of defective items. With this upgrade, the cost of producing each parka will be 85\$ and the percentage of defective items will be 5 percent. The rework cost and the percentage of defective items that can be reworked do not change with this upgrade.Calculate:Number of units reworked during the next year, with the current situation:

2) The Colonial House Furniture Company manufactures four-drawer oak filing cabinets in six stages. In the first stage, the boards forming the walls of the cabinet are cut; in the second stage, the front drawer panels are woodworked; in the third stage, the boards are sanded and finished; in the fourth stage, the boards are cleaned, stained, and painted with a clear finish; in the fifth stage, the hardware for pulls, runners, and fittings is installed; and in the final stage, the cabinets are assembled. Inspection occurs at each stage of the process, and the average percent ages of good-quality units are as follows.

StageAverage percentage of good

The cabinets are produced in weekly production runs with a product input for 400 units.The Colonial House Furniture Company has investigated the manufacturing process to identify potential improvements that would improve quality. The company has identified four alternatives, each costing \$15,000, as follows.Alternative 1: Only Stage 1 quality improves to 87 percent.Alternative 2: Stage 2 quality improves to 92 percent and Stage 4 quality improves to 91 percent. All the other quality percentages remain the same as the current situation.Alternative 3: Stage 5 quality improves to 89 percent and Stage 4 quality improves to 94 percent. All the other quality percentages remain the same as the current situation.Alternative 4: Only Stage 2 quality improves to 96 percent.What is the yield for each alternatives, if the company chooses to go with Alternative 1, 2, 3, 4,5,6

3) Backwoods American, Inc., produces expensive water-repellent, down-filled parkas. The company implemented a total quality-management program in 2016. Following are quality-related accounting data that have been accumulated for the three-year period after the program’s start. Numbers in each category are for 2017 until 2019, from left to right. For example, the prevention cost in 2017 is 28.3 and prevention cost in 2019 is 50.0.

Compute the company’s total failure costs as a percentage of total quality costs for each of the five years. Does there appear to be a trend to this result? If so, speculate on what might have caused the trend.Also Compute quality-sales indices and quality-cost indices for each of the five years. Is it possible to assess the effectiveness of the company’s quality-management program from these index values?You are just reporting the total failure costs as a percentage of total quality costs for each of the three years and quality indices as requested below.Always keep two decimal places. Report 81.36 percent as 81.36 and not 0.8136.Use two decimal places in your calculations.
