problem 1 Write a function to search an item named searchkey in an array of 20 elements. Assumed the array has all integer value and also the search item is an integer.

problem 2 Now consider the array is sorted. Modify the above script (from question 1) in a way so that dont have to search the item in every position of the array( not looking 20 times considering worst case scenario).

thanks in advance

Prove that the following problem is in NP: Given a digraph G over n vertices (n is an even number), does G contain 2 vertex-disjoint simple cycles in which each cycle is of length n/2?

A Private Poly Clinic in City wish to develop software to automate their Patient Monitoring system for storing the details of the patients visited the clinic. Develop a system to meet the following requirements:

Read the fees paid by ‘N’ patients into a one dimensional array in random order. Develop an algorithm, flow chart and write a C program to arrange the fees read in ascending order. Display the result with appropriate statements.

Assume the following declarations have been made:

-----------------------------------
char item[50];
char guess;

-----------------------------------
Furthermore, suppose that all of the elements of an item have already been initialized, and that the user has already entered a value for guess.

Write a code fragment to find and print out each index i for which item[i] is the same as guess.

Be sure to specify any additional necessary variable declarations.

As an example, consider the case where the rst 10 elements of item are (in order)
'a', 'b', 'c', 'd', 'a', 'b', 'b', 'c', 'f', 'a',

and the remaining elements are all 'y'. If guess were 'b', then your code should print out the following indices:
1 5 6

Python 3.5:

Consider the Account class that we developed previously.

Task 1:

Review the code in the constructor in the Account class. What happens if we attempt to make a new account with a negative balance? Use exception handling to raise an exception if a balance less that 0 is given. Add a message to the constructor saying "Warning! Your balance is equal to or less than 0!".

Task 2:

Next, in the Account class's withdraw() method, add code to check if the amount given exceeds the account's balance. If it does, then raise a ValueError. Add a message to the withdraw() method saying "ERROR: Insufficient funds!". The balance in the account should remain unchanged.

Also, add code to check if the amount of withdrawal is zero. You should raise a ValueError if the amount is less than or equal to zero.

Note: you must submit the entire class definition.

For example:

Account Code:

------------------------------------------------------

class Account:

def __init__(self, id, balance: int=None, annual_interest_rate: int=None):
if balance > 0:
self.__id = id
if balance == None:
self.__balance = 100
else:
self.__balance = balance
if annual_interest_rate == None:
self.__annualInterest = 0
else:
self.__annualInterest = annual_interest_rate
else:
raise ("Warning! Your balance is equal to or less than 0!")
def get_id(self):
return self.__id
def get_balance(self):
return self.__balance
def get_annual_interest_rate(self):
return self.__annualInterest
def get_monthly_interest_rate(self):
return (self.__annualInterest/12)
def get_monthly_interest(self):
return (self.__balance * (self.__annualInterest/12)/100)
def deposit(self, amount: int=None):
if amount == None:
deposit = 0
else:
deposit = amount
self.__balance = self.__balance + amount
return
def withdraw(self, amount: int=None):
if amount == None:
withdraw = 0
else:
withdraw = amount
self.__balance = self.__balance - withdraw
return
def get_balance(self):
return self.__balance

Instructions: Digital submission in PDF format (you can use Word or Markdown to create these and then convert to PDF). Your submission must include all R code.
I will be testing all of your code by copying and pasting into my R session, so make sure it works. Your solutions should be a narrative that incorporates R code (i.e. tell a story). R code by itself is not sufficient. This must be entirely an original work done by you. Copying someone else’s work (possibly found online) is not acceptable.

Assignment:

1) In homework 2, you gave the name of a site you would like to scrape. Follow through with this (you may change the site if you wish). The point of this exercise will be to ultimately provide an interesting visualization of the data which needs to be included in your solution. For this problem, the data must be scraped. Provide why you chose this site, and how someone would find your visualization useful (in other words, justify why anyone would care about this).

Given the information below, create the fully labeled Crow's Foot ERD using a specialization hierarchy where appropriate (use Visio). The ERD must contain all primary keys, foreign keys, and main attributes. Business rules are defined as follows: A small company sells products on-line. Each product is supplied by one supplier. Each supplier delivers only one product. Each product belongs to one of the following categories: Books, Movies, or CDs. All products have common attributes - a product code, a title and a price- and attributes that are unique for each group of products. The list of such attributes includes but is not limited to the following: the publisher name (books), the format (movies), and the rating (CDs). In addition, customers may purchase a book (hardcover or paperback) or its' electronic version. For regular books, the company wants to record the number of pages per book. For electronic books, the format and the size of the file must be recorded.

1, If we want to display output from a command, such as DIR or TYPE, one screen at a time, we can use what kind of command?

> MORE

| PAGE

| MORE

>> PAGE

2, To delete a directory that contains subdirectories and/or files, we will use what command:

DEL directory name /S

MD directory name /S

RD directory name /S

RMDIR directory name

3, When we are using certain tools (e.g. WMIC, DISKPART, and NETSH) in the Interactive Mode, most of the internal Command Prompt commands, such as CLS and CD, would not work. However, which command will work?

BYE

EXIT

| MORE

START

4, When we use this command in a batch file, the user must pick from the available options because Command Prompt won't let s/he pick anything else:

CHOICE

IF ELSE

FOR

SET

Hi Can someone explain how the the output was achieved in details for this java question?

public class Example
  
{
public static void main(String [] args)
{
int a = 6, b = 5, i , num1, num2;
for (i = 1; i <= 3; ++i)
{
num1 = method1(a, b);
num2 = method2 (a, b);
System.out.println (num1 + " " + num2);
a = a + 2;
b = b - 1;
}
}
public static int method1 (int c, int d)
{
c = c + d;
return c;
}
public static int method2 (int e, int f)
{
f = f + e * 2 ;
return f ;
}
}

Python

1. Change the order of an input string based on Unicode equivalent.

Write a function Reorder that will take an input string of a maximum length of 20 characters and create a new string that reorders the string based on it’s binary Unicode character equivalent, e.g. ‘a’ = 0x61, ‘A’ = 0x41, from smallest value to largest value. In this example, ‘A’ would come before ‘a’, as 0x41 is a smaller number than ox61. Note, use python logical operators to do the comparison. Do not try to create a Unicode lookup table. For your code, use the string “sum=(x*259)/average” as your input string to your function.
