PSUEDOCODE: Using whatever looping mechanism makes sense to you, create an algorithm that will display timing for a stopwatch.

Keep the following in mind:

• We can assume that you're processing on the world's oldest, slowest computer and that each iteration of a loop takes exactly one/100th of a second
• The user needs to see fractions of a second all the way to 24 hours - any more and we should really call for medical help...
• Provide a way for the user to be able to stop the procedure at any time

Write code that classifies a given amount of money (which you store in a variable named amount), specified in cents, as greater monetary units. Your code lists the monetary equivalent in dollars (100 ct), quarters (25 ct), dimes (10 ct), nickels (5 ct), and pennies (1 ct). Your program should report the maximum number of dollars that fit in the amount, then the maximum number of quarters that fit in the remainder after you subtract the dollars, then the maximum number of dimes that fit in the remainder after you subtract the dollars and quarters, and so on for nickels and pennies. The result is that you express the amount as the minimum number of coins needed.

Please show me how to do it in the jupyter notebook.

Given an alphabet Σ, what are the languages L over Σ for which L ∗ is finite? How many such languages exist?

Stack ADT

What would you say is the most important drawback of using the stack that should be considered before choosing it for use in a real application? Typed out please.

C++... How do I separate a C String, entered by a user, by commas? Say they enter Frog,Wolf,Spider... I want a array containing the elements {Frog, Wolf, Spider}

thanks

Here's my idea so far...

cout << "Enter the column names (c of them), each name seperated by a comma" << endl;

char colNames[100];

cin >> colNames;

for (int i = 0; i < 99; ++i){

if (colNames[i] == ','){

//parse the string, assign that string name to that column

}

}

cout << colNames << endl;

Create an Entity relationship diagram (ERD) conceptual model for this case.

VINEYARD HOLDINGS AND GRAPE VARIETIES

VVI’s vineyard sources its wine from ten plots of land in separate locations from two

acres to twenty acres. Each vineyard has its own unique name, such as Rattlesnake

Canyon, Red Fox, Theresa’s, etc. and is either owned by VVI or by an independent third

party. Each is managed by a single employee. No employee manages more than one

vineyard. The location and size, measured in acres, of each vineyard is recorded. Each

vineyard is dedicated to the growing of a single grape variety per vintage year. However,

over time a particular vineyard may be replanted to a different grape variety, depending

on market demand for particular types of wine. The winery maintains a record of these

plantings.

VVI currently grows six different grape varieties: Cabernet Sauvignon, Merlot,

Zinfandel, Pinot Noir, Chardonnay, and Sauvignon Blanc. Information that is specific for

each grape variety and must be recorded includes the juice conversion ratio, a measure of

how much juice, on average, can be extracted from a given weight of a grape variety. The

wine storage requirement, which is the type of storage container (typically either stainless

steel tank or oak barrel) used to hold the juice while it ferments into wine, is also

recorded for each grape variety, as is the wine aging requirement, which is the measure of

how long the wine produced from the juice should be stored before bottling. Certain

measures related to the grapes that vary with the specific vintage year harvest are also

recorded including the vineyard the grapes come from, the total amount (weight) of

grapes harvested, and the ripeness of the grapes (expressed in % sugar).

WINE PRODUCTS AND BOTTLES

Information on the wines created from the grapes must, of course, be recorded. Each

wine produced is given a unique identification number in addition to its name. Other

information recorded for each wine is its vintage year, category (e.g., dry red, dessert,

etc.), and percent alcohol, a legal requirement. Also recorded is the employee in charge of

making that wine. Wine makers may be responsible for more than one wine at a time.

The composition of a wine may be entirely from a single grape variety or may be a blend

of more than one variety. The proportion of juice from each grape variety for each wine

produced must be recorded. Several of the grape varieties are used in more than one

blended wine. None of VVI wines are vineyard specified; that is, the wines are labeled by

the grape varieties contained in the wines only, without reference to specific vineyard

plots.

The wines are sold in case lots. The winery refers to these case lots as products. A

product is a specific wine in a specific bottle size in a specific case quantity sold at a

specific price. Each product type is given a unique product identification number. VVI

does not sell partial cases, nor does it mix wines or bottle types in a single case.

The bottles used for the wines vary in capacity, shape, and glass color. Each bottle type is

assigned a unique bottle identification code. VVI maintains an inventory count of how

many of each bottle type is currently on hand in their warehouse. The winery prefers to

keep at least a month’s worth of bottle inventory on hand. The usual cost per bottle is also

recorded for each bottle type to aid in pricing the products and as a guide in calculating

expected future bottle order costs.

The bottles must be purchased from outside glass vendors. Each of these vendors is

assigned a unique identification number. In addition to this number, each vendor’s name,

address, and phone are recorded. Also recorded, for each vendor, is the name of the

principal contact (i.e., account representative) at the vendor that handles the VVI account.

Bottles are acquired from the vendors by placing orders. Some bottle types may be

ordered from more than one vendor. Each order involves only a single vendor but may

include more than one bottle type. Usually orders are filled completely by the vendors,

but occasionally an order must be filled with multiple shipments, due to a back-order

condition at the vendor. VVI maintains careful records of what quantities are ordered and

what quantities are received, as well as when the bottles are ordered and when they are

received, and the actual price charged for the bottles.

note: USE C++ WITH USER DEFINED FUNCTIONS AND RECURSIVE FUNCTION ONLY. No C++ library function is allowed.

The game of “Jump It” consists of a board with n positive integers in a row, except for the first
column, which always contains zero. These numbers represent the cost to enter each column.
Here is a sample game board where n is 6:
0 3 80 6 57 10
The object of the game is to move from the first column to the last column with the lowest total
cost.
The number in each column represents the cost to enter that column. You always start the game
in the first column and have two types of moves. You can either move to the adjacent column or
jump over the adjacent column to land two columns over. The cost of a game is the sum of the
costs of the visited columns.
In the board shown above, there are several ways to get to the end. Starting in the first column,
our cost so far is 0. We could jump to 80, then jump to 57, and then move to 10 for a total cost
of 80 + 57 + 10 = 147. However, a cheaper path would be to move to 3, jump to 6, then jump to
10, for a total cost of 3 + 6 + 10 = 19.

Write a recursive function that solves this problem and returns the lowest cost of a game board
represented and passed as an array.

Note: your function shouldn’t output the actual sequence of jumps, only the lowest cost of this
sequence.

IMPORTANT: Use only user defined functions. No C++ library function is allowed. Please write it in a simple and elementary way.

PYTHON

In this lab we will design a menu-based program. The program will allow users to decide if they want to convert a binary number to base 10 (decimal) or convert a decimal number to base 2 (binary). It should have four functions menu(), reverse(), base2(), and base10(). Each will be outlined in detail below. A rubric will be included at the bottom of this document.

Menu()

The goal of menu() is to be the function that orchestrates the flow of the program. menu() should be the first thing called and should do the following:

• Print a welcome message
• Print the following options:
  • 1. Convert Binary to Decimal
  • 2. Convert Decimal to Binary
  • 3. Quit
• Prompt the user for input
• Evaluate the input and execute the appropriate function call, break, or print “Invalid input” based as on the user input.
• The menu should continue looping until the user quits

Base2()

This function should take a number from the user and convert it into its binary representation then print it to the user. You can use your code from Lab1.

Base10()

This function should prompt the user for a binary number represented by a string and calculate the decimal number. Base10() should do the following:

• Prompt user for binary number
• Declare a sum variable and set it to zero
• Store the return value of a function call to reverse() (included below) into a variable (for the sake of example let’s call it st0.
• Use:

for i in range(0,len(st)):

            sum+=(int(st[i])*(2**i))

print(sum)

Remember that len returns the number of characters in a string and we can access a character by using the string name and an index number. st[0] would return the first character of the string in variable st. If we think about the conversion, we take the number and multiple by 2 raised to the power of the position number. If we reverse the string, we can use the index number as this position number because the string is indexed left-to-right. Which is the opposite of number positions are right-to-left. Thus, I can be used as our exponent.

Reverse()

#Name: Reverse

#Input: String s

#Output: String r

#Description: This function takes a string as input and reverses that string

#returning it as output.

def reverse(s):

r=""

for i in s:

    r=i+r

return r

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

  Enter input file name or full path: numbers.txt
  Enter output file name or full path: output.txt
  There were 18 numbers input, 10 output, and 8 duplicates. 

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.
