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. Ex. If the input is:

See Explanation Below

Explanation:

/ / C+ + printNumPattern () recursive method

/ / Comments are used for explanatory purpose

/ / Only the recursive is submitted

/ / Method starts here

void printPattern (int num1, int num2, bool dec)

{

/ / Print num2.

cout << num2 << " ";

//Printing to num1

if (dec = = false && num1 = =num2) {

return; }

/ / Printing to 0 or negative.

if (dec)

{

/ / If num2 is greater than num2

if (num2-num1 > 0)

printPattern (num1, num2-num1, true);

else / / recur with false dec

printPattern (num1, num2-num1, false);

}

else / / If dec is false.

printPattern (num1, num2+num1, false);

}

//End of recursive
