Question:

Continue making the following program using solution 2:

A spiral of numbers can start and end with any positive integers less than 100. Write a program which will accept two positive integers x and y as input, and output a list of numbers from xx to y inclusive, shown in a spiral.  You may assume that the end value is greater than or equal to the start value.

A spiral starts with the first number in the center. The next number appears immediately below the first number. The spiral continues with the numbers increasing in a counter-clockwise direction until the last number is printed.

Sample Input 1
10
27

Sample Output 1
      27 26
16 15 14 25
17 10 13 24
18 11 12 23
19 20 21 22

Sample Input 2
7
12

Sample Output 2
12 11
 7 10
 8  9

Hint of solution 2:
Use directions = ‘sdwa’ to solve the problem
We can create a variable called directionIndex and make it always equals to 0 to 3 which indicates the index in the variable direction.
