3. N-Queens. A Queen on a chessboard can attack any piece in the same column, row or diagonal. The N-Queens problem is to place n queens on a n x n chessboard such that no two queens threaten each other. a) Implement a one-dimensional integer array of Queen positions for an 8x8 board where indices represent rows and the values represent columns. For example, this "safe" solution would be {3,6,2,7,1,4,0,5} Q b) Request values for the array from the console. c) Implement an output to display the board (see output example). d) Implement a queensAreSafe function that: 1) Returns false if multiple queens share a column. Note that by design they are in separate rows (make sure you understand why). 2) Returns false if multiple queens share a diagonal. 3) Returns true if all queens are safe. e) Program should display if the Queens are safe or not safe. Example output (input is bold and italicized): Enter 8 column values: 14235760 Queens are not safe! (3,6,2,7,1,4,0,5, safe figure)

Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

3. N-Queens.
A Queen on a chessboard can attack any piece in the same column, row or diagonal.
The N-Queens problem is to place n queens on a n x n chessboard such that no two
queens threaten each other.
a) Implement a one-dimensional integer array of Queen positions for an 8x8 board
where indices represent rows and the values represent columns.
For example, this "safe" solution would be {3,6,2,7,1,4,0,5}
. Q

b) Request values for the array from the console.
c) Implement an output to display the board (see output example).
d) Implement a queensAreSafe function that:
1) Returns false if multiple queens share a column. Note that by design they are
in separate rows (make sure you understand why).
2) Returns false if multiple queens share a diagonal.
3) Returns true if all queens are safe.
e) Program should display if the Queens are safe or not safe.

c++ A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and outputs whether the input is a palindrome. If the input is bob, the output is: bob is a palindrome If the input is bobby, the output is: bobby is not a palindrome Hint: Start by just handling single-word input, and submit for grading. Once passing one single-word test cases, extend the program to handle phrases. If the input is a phrase, remove or ignore spaces. 356110.1926120.qx3zqy7

Write a program that will identify whether a given line of input is a palindrome or not. Your program must also be able to determine the following sample inputs as palindromes, aside from identifying one-word inputs: Able was I 'ere I saw Elba. Madam, I'm Adam. A man, a plan, a canal, Panama. These samples require that your program must ignore spaces and punctuations, and consider uppercase and lowercase letters to be the same. Include necessary functions in your program to process the input. You can also use existing functions from the string library.
