NQueensB: Write a brief Python program to generate a more-informed random solution to the N-Queens problem (described on pages 71-72). Your program should:

Prompt the user for a value for N (for an NxN board)

Generate a smarter randomized candidate NQ solution (unique rows & columns)

Count the number of conflicting pairs of queens

Repeat the previous two steps until you get a solution

Print the solution and the number of iterations the solution took
