Write a recursive function called print_num_pattern() to output the following number pattern. Given two positive integers as input (Ex: 12 3), subtract the second integer (3) from the first one (12) and print the result continually until 0 or a negative value is reached. Then continually print the result of the addition of the second integer to the last value you reached from the subtraction (zero or negative) until the first integer is reached again. Note: For this lab, do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12

In this lab, we will practice:
- Implementing recursive function
- printing in a recursive function (before and after the recursion function call)
- working on setting the base and general cases for the recursion function
Instructions
Write a recursive function called print_num_pattern() to output the following number pattern.
Given two positive integers as input (Ex: 12 3), subtract the second integer (3) from the first one (12) and print the result continually until 0 or a negative value is reached. Then continually print the result of the addition of the second integer to the last value you reached from the subtraction (zero or negative) until the first integer is reached again.
Note: For this lab, do not end output with a newline.
Ex. If the input is:
12 3
the output is:
12 9 6 3 0 3 6 9 12
Hint
- You do not need to actually do addition.
- You can write statements i.e. printing statements after the recursion function call.
