aleksley [76]

Answer:

Explanation:

The following is written in Java and prints out the pattern to and from the first num parameter that is passed to the function. Meaning it goes from num1 to 0 and then from 0 to num1 again. It prints all of the values in a single line seperated by a space and a test case was used using the values provided in the question. The output can be seen in the attached picture below.

static void printNumPattern(int n1,int n2){

       System.out.print(n1 + " ");

       if(n1<=0) {

           return;

       } else {

           printNumPattern(n1-n2,n2);

       }

       System.out.print(n1 + " ");

   }
