Write a program that gets an integer, n, from the user and then prints n repetitions of the pattern: some Bs, some As. Each new repetition has two less Bs and two more As than the pattern before it. The first pattern has 2*n+1 Bs and 1 A. Example: if the number from the user is n=3, then the program prints: BBBBBBBABBBBBAAABBBAAAAABAAAAAAA
