Write a recursive program Rul er to plot the subdivisions of a ruler using StdDraw as in Program 1.2.1.

Program 1.2.1 String concatenation example public class Ruler public static void main(String[] args) String rulerl- "1"; String ruler2 rulerl"2rulerl; String ruler3-ruler3" ruler2; String ruler4 ruler3"4"ruler3; System.out.println(ruler1); System.out.println(ruler2): System.out.println(ruler3); System.out.println(ruler4); This program prints the relative lengths of the subdivisions on a ruler. The nth line of output is the relative lengths of the marks on a ruler subdivided in intervals of 1/2" of an inch. For example, the fourth line of output gives the relative lengths of the marks that indicate intervals of one-sixteenth of an inch on a ruler. % javac Ruler, java % java Ruler 1 2 1 1 2 1 3 1 2 1 1 2 1 3 1 2 1 4 1 2 1 3 1 2 1 The ruler function for n 4 Program 1.2.1 String concatenation example public class Ruler public static void main(String[] args) String rulerl- "1"; String ruler2 rulerl"2rulerl; String ruler3-ruler3" ruler2; String ruler4 ruler3"4"ruler3; System.out.println(ruler1); System.out.println(ruler2): System.out.println(ruler3); System.out.println(ruler4); This program prints the relative lengths of the subdivisions on a ruler.
