8.18 LAB: Number pattern Write a recursive method called printNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. 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 318446.2220060.qxazay7 LAB 8.18.1: LAB: Number pattern 0/ 10 АCTIVITY NumberPattern.java Load default template. import java.util.Scanner; public class NumberPattern { // TODO: Write recursive printNumPattern () method public static void main (StringI] args) { Scanner scnr = new Scanner (System.in); int numl; int num2; num1 = scnr.nextInt (); num2 = scnr.nextInt (); printNumPattern (numl, num2);

# 8.18 LAB: Number Pattern ## Task Write a recursive method called `printNumPattern()` to output a specific number pattern. ### Instructions Given a positive integer as input (e.g., 12), subtract another positive integer (e.g., 3) repeatedly until 0 or a negative value is reached. Then, continually add the second integer until the first integer is reached again. Do not end the output with a newline for this lab. ### Example - **Input:** ``` 12 3 ``` - **Output:** ``` 12 9 6 3 0 3 6 9 12 ``` ### Code Implementation ```java import java.util.Scanner; public class NumberPattern { // TODO: Write recursive printNumPattern() method public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int num1; int num2; num1 = scnr.nextInt(); num2 = scnr.nextInt(); printNumPattern(num1, num2); } } ``` ### Explanation - **Objective:** Implement a recursive method to generate a number pattern based on the inputs given. - **Prototype:** `printNumPattern(int num1, int num2)` where `num1` is the starting integer and `num2` is the subtract/add integer. - **Logic:** Decrement `num1` by `num2` until the value is 0 or negative, then increment back to the original `num1`. ### Scoring - **Total Points:** 10 - **Current:** 0 Ensure to test your code thoroughly and handle boundary cases effectively.
