Given two input integers for an arrowhead and arrow body, print a right-facing arrow. Ex: If the input is: 0 1 the output is: 1 11 00000111 000001111 00000111 11 1   import java.util.Scanner;  public class LabProgram {   public static void main(String[] args) {      Scanner scnr = new Scanner(System.in);       int baseChar;       int headChar;             /* Type your code here. */   }}

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.
