Write a program that examines a series of a integers entered by the user and that then determines whether adjacent values in the series differ by at most 2.

The program should ask the user to enter the number , n, of numbers in the sequence, followed by the numbers themselves (i.e. one per line). The assumption is that n>1.

Hint: The function abs(-5) will return 5.

Sample Input/Output:

Enter the length of the sequence:

3

Enter the number 1:

50

Enter the number 2:

51

Within bounds
