Please follow the steps to write a small project

This is the code that was done before:

Step$1$: Transform General class into an abstract class$$

$$

abstract class General$($val name: String$)\{$

val maxHP: Int $=4$

var currentHP: Int $=0$

init $\{$

println$("$General $name created."$)$

$\}$

$\}$

Step $2$: Implement Simple Factory Pattern$$

$$

object GeneralFactory $\{$

fun createGeneral$($name: String$)$: General $\{$

return when $($name$)\{$

"LiuBei" $->$ LiuBei$($name$)$

"CaoCao" $->$ CaoCao$($name$)$

"SunQuan" $->$ SunQuan$($name$)$

else $->$ throw IllegalArgumentException$("$Unknown general name"$)$

$\}.$apply $\{$

currentHP $=$ maxHP

println$("$$name has $maxHP health point."$)$

$\}$

$\}$

$\}$

Step $3$: Implement Factory Method Pattern$$

$$

abstract class GeneralFactory $\{$

abstract fun createRandomGeneral$()$: General

$\}$

class LordFactory : GeneralFactory$()\{$

private val generatedGenerals $=$ mutableSetOf$()$

override fun createRandomGeneral$()$: General $\{$

val possibleGenerals $=$ listOf$("$LiuBei$",$ "CaoCao", "SunQuan"$)$

val availableGenerals $=$ possibleGenerals.filter $\{$ it $!$in generatedGenerals $\}$

val randomGeneralName $=$ availableGenerals.random$()$

generatedGenerals.add$($randomGeneralName$)$

return GeneralFactory.createGeneral$($randomGeneralName$)$

$\}$

$\}$

$//$ NonLordFactory can be similarly implemented if needed

Final Step: Modify main function to use factories and add generals to the manager

fun main$()\{$

val manager $=$ GeneralManager

val liuBei $=$ GeneralFactory.createGeneral$("$LiuBei$")$

val caoCao $=$ GeneralFactory.createGeneral$("$CaoCao$")$

val sunQuan $=$ GeneralFactory.createGeneral$("$SunQuan$")$

manager.addGeneral$($liuBei$)$

manager.addGeneral$($caoCao$)$

manager.addGeneral$($sunQuan$)$

val lordFactory $=$ LordFactory$()$

for $($i in $1.\mathrm{.}3)\{$

val newLord $=$ lordFactory.createRandomGeneral$()$

manager.addGeneral$($newLord$)$

$\}$

val nonLordFactory $=$ NonLordFactory$()$

for $($i in $1.\mathrm{.}3)\{$

val newNonLord $=$ nonLordFactory.createRandomGeneral$()$

manager.addGeneral$($newNonLord$)$

$\}$

val totalGenerals $=$ manager.getGeneralCount$()$

println$("$Total number of generals: $totalGenerals"$)$

$\}$
