Convert the following Java code in Chapel and add methods which would turn a lamp on and off, and another one which could show the status of a lamp. class Lamp { boolean ison; void turnOn() { ison = true; void turnOff() { ison = false; class ClassObjectsExample { public static void main(String[] args) { Lamp 11 = new Lamp();

Analyze the following code.public class Test { public static void main(String[] args) { System.out.println(m(2));  } public static int m(int num) { return num; }  public static void m(int num) { System.out.println(num); }} What can you say about the above code? Does it run? Does it compile? Any output?

Given string inputStr on one line and integers idx1 and idx2 on a second line, output "Match found" if the character at index idx1 of inputStr is equal to the character at index idx2. Otherwise, output "Match not found". End with a newline. Ex: If the input is: eerie 4 1 then the output is: Match found Note: Assume the length of string inputStr is greater than or equal to both idx1 and idx2.
