Write a program that implements Newton’s method to compute and display the square root of a number, x, entered by the user. The algorithm for Newton’s method follows: Read x from the user Initialize guess to x/2 While guess is not good enough do Update guess to be the average of guess and x/guess When […]

A string is a palindrome if it is identical forward and backward. For example “anna”, “civic”, “level” and “hannah” are all examples of palindromic words. Write a program that reads a string from the user and uses a loop to determine whether or not it is a palindrome. Display the result, including a meaningful output

There are numerous phrases that are palindromes when spacing is ignored. Examples include “go dog”, “flee to me remote elf” and “some men interpret nine memos”, among many others. Extend your solution to Exercise 75 so that it ignores spacing while determining whether or not a string is a palindrome. For an additional challenge, further

Write a program that converts a binary (base 2) number to decimal (base 10). Your program should begin by reading the binary number from the user as a string. Then it should compute the equivalent decimal number by processing each digit in the binary number. Finally, your program should display the equivalent decimal number with

Write a program that reads numbers from the user until a blank line is entered. Your program should display the average of all of the values entered by the user. Then the program should display all of the below average values, followed by all of the average values (if any), followed by all of the

When writing out a list of items in English, one normally separates the items with commas. In addition, the word “and” is normally included before the last item, unless the list only contains one item. Consider the following four lists: apples apples and oranges apples, oranges and bananas apples, oranges, bananas and lemons Write a

In order to win the top prize in a particular lottery, one must match all 6 numbers on his or her ticket to the 6 numbers between 1 and 49 that are drawn by the lottery organizer. Write a program that generates a random selection of 6 numbers for a lottery ticket. Ensure that the

Create a program that determines and displays the number of unique characters in a string entered by the user. For example, Hello, World! has 10 unique characters whilezzzhas only one unique character. Use a dictionary or set to solve this problem. Create a program that reads a duration from the user as a number of

Two words are anagrams if they contain all of the same letters, but in a different order. For example, “evil” and “live” are anagrams because each contains one “e”, one “i”, one “l”, and one “v”. Create a program that reads two strings from the user, determines whether or not they are anagrams, and reports

The notion of anagrams can be extended to multiple words. For example, “William Shakespeare” and “I am a weakish speller” are anagrams when capitalization and spacing are ignored. Extend your program from Exercise 143 so that it is able to check if two phrases are anagrams. Your program should ignore capitalization, punctuation marks and spacing
