The following program contains a logic error. Describe where to insert the appropriate debugging statements to help locate the error: import java. util. Scanner; public class AreaTriangle\\{ public static void main(String [] args) \\{ double base, height, area; Scanner reader = new Scanner (System. in); System.out.print("Enter the base of the triangle:"); base \(=\) reader nextDouble( ); system.out.print("Enter the height of the triangle: "); height = reader.nextDouble(); area \(=\) base \(+\) height \(/ 2\); system.out.println("The area is " + area);

Section 5.2, Modifying Lists, on page 85 said that strings are immutable. Why might mutable strings be useful? Why do you think Python made them immutable?

A simple undirected graph is complete if it contains an edge between every pair of distinct vertices. What does a depth-first search tree of a complete graph look like?

Let \(f(x)=x^{2},\) where \(-3 \leq x \leq 3 .\) Use a rotation matrix to rotate the graph of the function through an angle of \(90^{\circ} .\) Plot the original and rotated graphs on the same axes. Include a legend.
