#Python:

1. A palindrome is a sequence of characters that reads the same backwards as forwards. For example, ‘Eve’, ‘madam’, and 20502, are palindromes. Write a function called testPalindrome() that asks the user to input a string and returns if that string is a palindrome with the output as follows, without red:

>>>

Please enter a string: eve

Your string "eve" is a palindrome.

>>> testPalindrome()

Please enter a string: end

Your string "end" is not a palindrome.

>>> testPalindrome()

Please enter a string: 100921

Your string "100921" is not a palindrome.

>>> testPalindrome()

Please enter a string: 10401

Your string "10401" is a palindrome.

>>>

CODE IN C++ PLEASE

Write a program to implement the algorithm that you designed in Exercise 19 of Chapter 1. Your program should allow the user to buy as many items as the user desires. Instructions for Exercise 19 of Chapter 1 have been posted below for your convenience. Exercise 19 Jason typically uses the Internet to buy various items. If the total cost of the items ordered, at one time, is $200 or more, then the shipping and handling is free; otherwise, the shipping and handling is $10 per item. Design an algorithm that prompts Jason to enter the number of items ordered and the price of each item. The algorithm then outputs the total shipping and handling fee, and the billing amount. Your algorithm must use a loop (repetition structure) to get the price of each item. (For simplicity, you may assume that Jason orders no more than five items at a time.) An example of the program is shown below: Enter the number of items ordered: 3 Enter the price of item no. 1: 79.00 Enter the price of item no. 2: 23.50 Enter the price of item no. 3: 1.99 The shipping and handling fee is: $30.00 The billing amount is: $134.49 Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.

In java based on the classes provided finish the program per the requirements:

package cardgame;

private String suit;// spades,diamonds,clubs,hearts
private int value; // 1 to 13
public static final String[] SUITS ={"clubs","hearts","diamonds","spades"};
/**

*/
public String getSuit() {
return suit;
}

/**
* @param suit the suit to set
*/
public void setSuit(String suit) {
this.suit = suit;
}

/**
* @return the value
*/
public int getValue() {
return value;
}

/**
* @param value the value to set
*/
public void setValue(int value) {
this.value = value;
}
//you have to write two methods for random generation of suit and value
public int ranSuit()
{
int value= (int)(Math.random()*4)+0;
return value;
}
public int ranValue()
{
int value= (int)(Math.random()*13)+1;   
return value;
}
}

CardGame[] magicHand = new CardGame[7];//array of objects
for(int i=0;i<magicHand.length;i++)

c1.setValue(c1.ranValue());//random number 1 to 13
c1.setSuit(CardGame.SUITS[c1.ranSuit()]);

for(int i=0;i<magicHand.length;i++)
{
System.out.println(magicHand[i].getSuit() +" "+ magicHand[i].getValue());

// take input suit and value from user. compare with array.if same card is
//in the array print your card is found.

Digital security is an increasing concern is the Internet age. In order to protect sensitive information online, what are the methods for enhancing digital security? Select one method and describe in detail how it is implemented and how you would implement it to protect your online data.

Respond to the following in a minimum of 175 words:

The flow of a program is controlled by different structures. The three basic control structures in computer programs are sequence structures, decision structures (also called selection structures), and repetition structures (also called iteration structures).

Discuss the differences between decision structures and repetition structures used in algorithms. Provide examples of when you might use each.

Write a version of the binary search algorithm that can be used to search a string vector object. Also, write a program to test your algorithm. (Use the selection sort algorithm you developed in Programming Exercise 12 to sort the vector.) Your program should prompt the user to input a series of strings, ending the input stream with zzz. The program should then prompt the user to search for a specific string in the list. If the string is found in the list:

 x is found in the list

else:

x is not in the list

C# programming

Create a classes called AlphabetDice that simulates a multi-sided dices with alphabet characters on each side. For instance, a 10-sided AlphabetDice will random return 'a','b','c','d','e','f','g','h','i' or 'j'.

The custom constructor should require a random seed and the number of sides.

It should also have the following:

• A read-only property Sides that give us the number of sides
• A method char Next() that returns an appropriate random character (char)

On a side note, to cast an integer to a char, use (char). e.g.

int x = 66;

char c = (char) x;

You can use the following in main to test your class:

AlphabetDice d = new AlphabetDice(999,4); // 999 is the seed

Console.WriteLine(d.Sides);

for(int i=0;i<100;i++)

     Console.WriteLine(d.Next());

If your class is correct, adding the following line to the end of main should cause a compilation error:

d.Sides = 100;
