Procedures for Lab

Labs will be run asynchronously during the week that they are assigned for. You are welcome to work with a partner to complete the lab. You can have your progress evaluated after any subset of the milestones are completed. The labs are designed to be able to be completed in about an hour. You have until the end of Friday to get all your milestones checked off $($unless you request an extension$).$ The office hours schedule, including locations, is located on Canvas. We suggest you get your milestones checked off as soon as you complete them since Friday office hours tend to become extremely crowded. You will only receive credit for the milestones you have checked off by a TA$.$

Introduction

Welcome to our third week of CSCI $1933!$ This lab will introduce the Scanner class and get you more familiar with how arrays work, as well as giving you more practice on recursive and iterative algorithms.

$1$ Find the Maximum Digit in a Number

In this section, you will find the maximum digit in a given positive int both recursively and iteratively. Write a Max class which will have the following methods:

$$ public static int recursiveMaxDigit$($int num$)-$ This will find the maximum digit in num recursively

$$ public static int iterativeMaxDigit$($int num$)-$ This will find the maximum digit in num iteratively

Add test cases of both methods into your main method.

Hint: Use integer division $[/]$ and the modulo $($remainder$)$ operation $[\%]$ to separate out the individual digits. For example, $1634/10=163$ and $1634\%10=4$ using Java logic.

Example Test Cases:

$$ recursiveMaxDigit$(578)$ will return $8$

$$ recursiveMaxDigit$(10)$ will return $1$

$$ iterativeMaxDigit$(9999)$ will return $9$ iterativeMaxDigit$(13442)$ will return $4$

CSCI $1933$ LAB $22.$ WORKING WITH SCANNER

Milestone $1$:

Show a TA your code for recursiveMaxDigit$($int$)$ and iterativeMaxDigit$($int$)$ and show your test cases running successfully.

$2$ Working with Scanner

Over the course of this lab, you may have been slightly bothered by how often you are required to recompile. Every time you change your code, even if it$$s just to slightly change, say, the input to your recursiveMaxDigit$($int$)$ method you$$ll have to recompile. There is$,$ however, a better way to do this. We can use the Scanner class.

First off, you$$ll need to import the Scanner class. This is what allows you to use the class in your program. To do this, at the very top of your file, even above the public class Max line, you should add this line:

import java.u
